Filter_Signal

Version 1.0.0.0 by Lawrence Rabiner

Design FIR lowpass/bandpass/highpass filter and filter speech signal.

A standard operation when processing signals is to lowpass/bandpass/highpass filter a speech signal in order to eliminate extraneous low and high frequency components, such as DC offset, hum, and
