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

to reject unwanted frequencies while maintaining low

group delay variation in the passband. The equalizing

shape over the passband is |x/sin x|

and fs=50.0 MSPS (sampling rate).
