What do you mean by recursive filter?
In signal processing, a recursive filter is a type of filter which re-uses one or more of its outputs as an input.
What is recursive and non recursive filters give examples?
A non recursive filter is that in which the current output (yn) is calculated solely from the current and previous input values (xn, xn-1, xn-2, …). A recursive filter is one which in addition to input values also uses previous output values. These, like the previous input values, are stored in the processor's memory.
What is moving average filtering?
Moving Average Filter is a Finite Impulse Response (FIR) Filter smoothing filter used for smoothing the signal from short term overshoots or noisy fluctuations and helps in retaining the true signal representation or retaining sharp step response.
