The Comstron Model PSC-4490 is a Nyquist bandpass filter used in a DAC( digital to analog converter). The purpose of the filter is to normalize the amplitude response of an input ô(Sin x)/xô signal spectrum, and to reject unwanted frequencies while maintaining low group delay variation in the passband. The equalizing shape over the passband is |x/sin x|2 where and fs=50.0 MSPS (sampling rate).
