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 the magnitude response of a filter?
The magnitude response of filters can be characterized in terms of the frequency bands the filter will pass or reject. In Fig. 4.9 the ideal magnitude responses of the four most frequently used filter types are illustrated as a function of ω in radians per second.
What is the frequency response of a moving average filter?
Frequency Response of the Running Average Filter
H(ω) = (1/L) (1 − e− jω L)/(1 − e− jω).
How do you calculate frequency response magnitude?
First we substitute s = jω into H(s) to obtain an expression of the frequency response. Note that the numerator and the denomator are both complex. To obtain the amplitude response, we take the absolute value of H(jω). To do this, we evaluate the magnitude of the numerator and the denominator separately.
