Topics
Compute and display frequency responses of IIR and FIR lowpass, highpass, and bandpass filters.
Extract the phase response of a filter.
Measure the average time delay of a filter as a function of frequency.
Find and visualize poles and zeros of a linear system.
Generate and display the impulse response of a simple filter.
Compensate for the Delay Introduced by an FIR Filter
Use indexing to counteract the time shifts introduced by filtering.
Compensate for the Delay Introduced by an IIR Filter
Remove delays and distortion introduced by filtering, when it is critical to keep phase information intact.
