DESCRIPTION

•

INVERSE SINC, SQUARE ROOT NYQUIST

( ARBITRARY SHAPING AVAILABLE)

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
