Unformatted text preview: cutoff frequencies found in Part 1 and those found from your MATLAB plot. On your MATLAB plot label: ü༏ The audio range 20 Hz – 20 kHz, and ü༏ The usual frequency range of human voices 300 Hz – 3.5 kHz. Briefly discuss which of these 4 filters are useful for separating signals within the audio range (if a filter blocks all sounds or passes all sounds it would be useless).

Type of filter; Amplitudes of output signals in mVppk Frequency of...
