DESCRIPTION
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
(Sin x)/x
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|
