Abstract: An apparatus for determining one or more calibration values of an ADC is configured to receive a first reference signal and a second reference signal and apply to the ADC the following: over a first signal application period, a first ADC input signal including the first reference signal; over a second signal application period, a second ADC input signal having a substantially equal magnitude and an inverse polarity to the first ADC input signal; over a third signal application period, a third ADC input signal including the second reference signal; and over a fourth signal application period, a fourth ADC input signal having a substantially equal magnitude and an inverse polarity to the third ADC input signal. The apparatus is configured to determine the one or more calibration values based, at least in part, on an ADC output signal of the ADC over the four signal application periods.

Abstract: RF repeater circuits may be used to regenerate an RF signal. A method and apparatus is described for regenerating a received RF signal the RF signal comprising a plurality of channels, each channel comprising a plurality of channel symbols, the method comprising producing a digitized RF signal from the received RF signal, extracting spectral information of each of the channels from the digitized RF signal, recovering one or more channel symbols from each of the plurality of channels, remodulating the channel symbols, and converting the remodulated channel symbols to an analog signal resulting in a regenerated RF signal.
