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 noise which are often created during the recording process. This exercise describes a MATLAB exercise for designing an appropriate FIR filter (based on user specifications) and then filtering the speech signal using the designed filter. The file '1.8 Filter Signal.pdf' provides a User's Guide for this exercise.
