A method for transmitting and/or receiving a potential aggressor audio signal includes a transmission and/or a reception of successive groups of data timed by a first clock signal within respective successive frames synchronized by a second clock signal. In the presence of a risk of interference of the potential aggressor audio signal with a different, potential victim, signal, during the transmission or reception of the potential aggressor audio signal, the frequency of the first clock signal is modified while keeping the frequency of the second clock signal unchanged.

A payment terminal has a clock management unit for providing clock signals to components of the payment terminal. The payment terminal also has a wireless communication interface for communicating wireless signals. A processing unit of the payment terminal may monitor operation of a wireless communication interface of the payment terminal and, when the payment terminal is communicating wirelessly, modify an initial clock signal provided to one or more components of the payment terminal that emit RF noise to modify a frequency at which the RF noise occurs. When the payment terminal is no longer transmitting, the processing unit may provide the initial clock signal to the RF noise source.

Techniques are disclosed for determining propagation delay of a first path and or of a second path which connect a first transceiver unit associated with a first clock to a second transceiver unit associated with a second clock in a communications network, based on a first time reference representing a time of transmission of a first signal from the first transceiver unit, a second time reference representing the time of receipt of the first signal at the second transceiver unit, a third time reference representing a time of transmission of a reply to the second signal from the second transceiver unit, and a fourth time reference representing the time of receipt of the reply to the second signal at the first transceiver unit.

Techniques are provided for providing Doppler correction. In particular, embodiments may provide re-banding circuitry having a reference clock, a mixer, and a compensation circuitry for re-banding and for Doppler correction. The compensation circuitry may be configured to adjust a reference frequency of the reference clock based on signals received from a Global Navigation Satellite System (GNSS) receiver. The mixer may be configured to translate communication signals in a first frequency band to a second frequency band based at least in part on the adjusted reference frequency of the reference clock.

An integrated circuit comprises a timebase generator that comprises a linear feedback shift register (LFSR) and a switch mode direct current-to-direct current (DC-to-DC) voltage converter coupled to the timebase generator.

A receiver may receive a signal and process each of a plurality of sub-bands of the received signal via a respective one of a plurality of first-type receive chains. The receiver may utilize a signal output by a first one of the plurality of the first-type receive chains to remove undesired signals from a signal output by a second one of the plurality of the first-type receive chains. The undesired signals may comprise aliases and/or harmonics of one or more signals that fall within a sub-band of the first one of the plurality of the first-type receive chains. The receiver may downconvert, filter, and digitize each of the plurality of sub-bands via a corresponding one of the plurality of the first type receive chains. The received signal may encompass the cable television band, and each of the plurality of sub-bands may comprise a plurality of cable television channels.
