What are feedback filters?
Feedback causes a frequency-dependent change in amplitude, which can be used for various types of filters. Feedback filters are also described as infinite impulse response (IIR) filters because feedback causes the system's impulse response to theoretically last indefinitely.
What is a feedback comb filter?
The feedback comb filter is a simple type of infinite impulse response filter. If stable, the response simply consists of a repeating series of impulses decreasing in amplitude over time.
What is a feedforward filter?
Feedforward Filters. Filters combine delayed versions of signals and signals are made up of phasors. Therefore, understanding the effect of delaying a phasor is key to everything. there is to know about filters.
