Abstract
A sample and hold network is provided having an analog multiplier that multiplies the analog input signal by a sinusoidal strobe signal to produce a multiplied signal. The multiplied signal is filtered by a bandpass differentiating filter and is combined in a differential amplifier with the analog input signal to yield a periodically sampled and held version of the analog input signal. The bandpass differentiating filter attenuates or eliminates undesirable DC and frequency components.
