CONCEPTUAL WORKING OF INVENTION DRAWINGS
(FIG. 6A) and (FIG. 11A)
(40)
(41) This above example shows that each cycle of carrier is carrying its peak amplitude value which can be treated as sample value of modulating signal. It shows that peak value of each sine wave cycle of carrier wave acts as sample value of modulating signal and just the peak value of each carrier cycle is needs to reproduce original signal as long as the carrier frequency is sufficiently higher. For all practical purposes a better and appropriate filter needs to be used.
(42) Keeping above example in mind following explanation in detail of the waveforms shown in (
(43) The embodiment of
(44) In an embodiment of the invented transmission process we generate one pure sine wave cycle at carrier frequency starting at zero crossing point and ending at another zero-crossing point for every transition. Between the transitions we generate zero voltage cycles which represent no transition in the modulating signal. Or to say we are either generating a pure sine wave cycle or generating nothing ensuring there are no side bands produced.
(45) The AES3 signal waveform is shown in (FIG. 6A2) with its bit clock shown for reference only in (FIG. 6A1). The actual data value is marked in (FIG. 6A3) which is coinciding with transitions. In accordance with an embodiment of the present invention, steps of converting each transition in input signal in to one 0° to 360° pure sine wave cycle, starting at zero crossing point and ending at subsequent zero crossing point at the carrier frequency are shown in FIG. 6A4 to FIG. 6A8.
(46) Data edge extractions waveform is shown in (FIG. 6A4). Carrier frequency clock is shown in (FIG. 6A5), which provides timing information to generate one cycle gate pulse corresponding to each transition in signal as shown in (FIG. 6A6). This pulse is used further to generate a ground centred square wave cycle, having half positive going and half negative going cycle. This ground centred wave cycle of (FIG. 6A7) is further passed through a filter to generate one pure sine wave cycle. (FIG. 6A8) shows the modulated sinusoidal carrier wave with zero side bands. Sine wave cycle (pure) of (FIG. 6A8) achieves the inventive step of starting carrier sine wave cycle at zero voltage crossing point and ends the carrier cycle at zero crossing point, only after completing one 0° to 360° pure sine wave cycle at the carrier frequency. Amplitude of the sine cycle is defined at the beginning of sine cycle. It uses zero voltage cycles for remaining time.
(47) Thus, generated waveform of (FIG. 6A9) is similar to an “amplitude modulated wave form” with only two amplitude value, one is the amplitude of generated sine wave cycle and other being zero voltage cycle with zero amplitude. The sine wave cycles generated are configured to generate only pure carrier sine wave cycles with zero side bands. It is immaterial if the sine wave cycle starts with opposite polarity, as long as the cycle is a full sine wave cycle at carrier frequency as per appended claims. This invented method/system only generate modulated sine wave carrier cycles and does not generate any side bands is shown in (FIG. 6A9) which carries all the signal information within carrier frequency itself.
(48) The key inventive step is to start each individual carrier cycle with its one or more properties defined, in proportion to modulating signal at cycle starting zero crossing point and end the cycle at consecutive zero crossing point on completion of one pure sine wave cycle, in a cycle by cycle generation process. Modulating signals can change property of carrier wave sine cycle only at the cycle start zero crossing point, for each complete sine wave cycle of the carrier. Generation of each sine wave cycle can only start with its properties defined at start of each cycle and once the sine wave cycle generation starts, it's property cannot be changed by modulating signal during the cycle. In the invented steps zero voltage cycles are valid cycles.
(49) The invented transmission system does not have any side bands and thus it does not need any channel bandwidth, its maximum bandwidth capacity to carry wide band signals is much higher. The maximum bandwidth capacity of transmission system to carry wide band signals is also proportionate to the carrier frequency.
(50) Modulating signal bandwidth capacity of the invented transmission system for faithful reception can be derived from nyquest theorem. The Nyquist Sampling Theorem states that: an analog signal waveform may be uniquely reconstructed, without error, from samples taken at equal time intervals. The sampling rate must be equal to, or greater than, twice the highest frequency component in the analog signal.
(51) The receive system wave forms are shown in (
(52) In a receiver embodiment of the present invention, amplitude of each sinusoidal carrier wave cycle (FIG. 11A2), received carries 1 bit data, representing transition in the original modulating signal. This one bit signal is recovered by slicing the selected, filtered, amplified modulated sinusoidal carrier waves with zero side bands and generate a logic pulse, representing the transition. This square pulse is used to toggle a flip flop to produce the original AES3 wave form shown in FIG. 11A7.

(115) TABLE-US-00001 PM Phase Phase Shift Keying in conventional term is achieving modulation modulation by changing the phase angle of the carrier sine or PSK wave in response to modulating signals. This type of Phase shift modulation has many variants and one of the most Keying popularly known being QPSK (Quadrature Phase Shift Keying). All the variants need bandwidth in proportion to highest signal/data frequency and have evolved over time for specific applications with advantages. All variants of PSK either alone or in combination with other properties like amplitude or frequency can benefit from method and system of the present invention. Variants include but not limited to: -BPSK (binary phase- shift keying), (DBPSK (differential BPSK). DPSK (differential phase-shift keying), QPSK (Quadrature Phase Shift Keying), DQPSK (differential phase-shift keying), QAM (quadrature amplitude modulation), OFDM modulation, OFDM with QPSK. OQPSK also known as SQPSK (Offset Quadrature Phase Shift Keying), BPSK or PRK, phase reversal keying, or 2PSK, SOQPSK (shaped-offset QPSK), Continuous phase modulation (CPM) and many more fine variants of these. OOK (ASK) Amplitude-shift keying is the most basic and one of On Off the earliest modulation schemes. It basically switches ON Keying or OFF the basic carrier itself under control of the modulating signal which is mostly digital or manual. Variants include but not limited to: - ASK Amplitude Shift Keying, it is frequently used in optical communication systems. With addition phase shift to it, becomes APSK. AM Amplitude modulation is quite common and is Amplitude implemented by variation of the carrier wave amplitude in Modulation response to modulating signal. Variants include but not limited to: - double side band, Single Side band, Vestigial side band, suppressed carrier and variants of this. In addition, its combinations with Phase Shift and frequency shift are also there. FM FM is a method of transferring information by changing frequency in proportion to the modulating signal. It is widely used in broadcasting and other communication systems independently. FM can also be combined with AM and other modulation processes to conserve transmission bandwidth. Variants include but not limited to: Frequency Modulation, FSK is another form of frequency modulation. Multiple frequency shift keying and minimum shift keying are the other variants of FM with additional parameters. MFSK system is dual-tone multi-frequency (DTMF), OFDM is a frequency-division multiplexing (FDM), QPSK, and others QAM and Phase Modulation in combination to amplitude and other frequency are used in modern digital communication combinations systems. Its most popular variant is with its combination with amplitude modulation known as QAM and its variants.
The present invention has various advantages. The system and method can provide solution for transmission of data and high bandwidth signals using narrow channel band width up to zero hertz. Another advantage includes production of zero sidebands, which results in carrier frequency itself carrying the vast amount of data and other signals offering better utilization of spectrum bandwidth. In other words, more information can be transmitted using limited spectrum up to a single frequency. Another advantage of the invention is reduction in noise density for the received carrier signals. The advantage will majorly depend on use of technique to limit the bandwidth of received channel in practice to below 100 Hz or 10 Hz. For a received device bandwidth reduction from 10 KHz to 100 Hz will provide a noise floor reduction of about 40 dB.
