Abstract
A sample and hold network samples an input data signal at a periodic rate by differentiating the input data signal and multiplying it in an analog multiplier by a strobe signal, whose spectrum extends to at most twice the highest frequency in the data input signal. The output of the multiplier is combined in a differential amplifier with the input data signal to provide an output having a slope which is zero and also equal to the input data signal at times that are integral multiples of the period of the strobe signal.
