How do you implement FIR?
An FIR filter can be easily implemented using just three digital hardware elements, a unit delay (a latch), a multiplier, and an adder. The unit delay simply updates its output once per sample period, using the value of the input as its new output value.
How to use Firpm in Matlab?
If you specify an odd-valued n , firpm increments it by 1. b = firpm(n,f,a,w) uses the weights in vector w to weight the fit in each frequency band. The length of w is half the length of f and a , so there is exactly one weight per band. b = firpm(n,f,a,w) is a synonym for b = firpm(n,f,@ firpmfrf ,a,w).
How to plot frequency response of FIR filter in Matlab?
h = freqz(___, f , fs ) returns the frequency response vector h evaluated at the physical frequencies supplied in f . freqz(___) with no output arguments plots the frequency response of the filter.
