What will be the response of a moving average filter?
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.
What is attenuation in filter?
Attenuation – an amplitude loss, usually measured in dB, incurred by a signal after passing through a digital filter. Filter attenuation is the ratio, at a given frequency, of the signal amplitude at the output of the filter over the signal amplitude at the input of the filter, defined as. (F-1)
What is the cutoff frequency of a moving average filter?
The cutoff frequency is defined as the frequency of the half-power point, where the power gain is a half. It's often called the − 3 d B -point, because 10 log 10 ( 1 2 ) ≈ − 3.01 d B .
How do you determine the size of a moving average window filter?
The window size of a moving average filter is determined by the number of points to be used in computing the average. This number is usually referred to as the “order” of the filter.
