A method for processing continuous sensor signals of a sensor in which a sensor signal is sampled at a sampling frequency and a series of sampled values able to be classified in terms of time is generated in this way, the sampling frequency is dynamically adapted to the spectral signal properties of the sensor signal variable over time and an item of time information is allocated to the thereby generated sampled values, which allows an allocation of the sampled values in terms of time.

A digital-to-analog converter system has digital-to-analog converters, a common output, and a digital controller for transmitting first codes to one of the converters at a radio-frequency digital rate, and for transmitting second codes to another one of the converters at the same rate. The digital controller includes a timing system for operating each converter at the digital rate in a return-to-zero configuration, such that a signal from the first converter is transmitted to the common output while the second converter is reset, and vice versa. The digital-to-analog converter system can generate a radio-frequency analog signal having signals in first and second Nyquist zones simultaneously.

Waveform-coding is applied to map successive on-off-keying (OOK) data bits onto successive multicarrier modulated symbols in time domain, wherein each multicarrier modulated symbol includes a set of sub-carriers in which alternating sub-carriers are set to non-zeros and zeros in frequency domain. The waveform coded multicarrier modulated symbols are up-converted to a carrier frequency to provide a data signal that is transmitted over a wireless channel.

A novel non-uniform sampling technique for a burst type signal. The analog signal is digitized with high sampling rate to maintain harmonics at higher frequencies and consequently the integrity of the analog signal. Then by using non-uniform sampling technique the most significant samples are selected for further processing which results in overall cost and power consumption reduction.

A device includes a voltage converter and an analog to digital converter (ADC). The voltage converter includes an input to receive a first voltage and an output to output a second voltage based on a switching signal having a first discrete converter frequency and a second discrete converter frequency. The ADC is coupled to and proximate to the voltage converter. The ADC includes a digital filter configured to substantially attenuate a first filter frequency and a second filter frequency. The voltage converter further includes a frequency control device configured to set the first discrete converter frequency and the second discrete converter frequency so that the first discrete converter frequency is approximately equal to the first filter frequency and the second discrete converter frequency is approximately equal to the second filter frequency.
