Designs a least-squares linear FIR filter.
y = fir_lsq(n, f, a)
y = fir_lsq(n, f, a, w)
y = fir_lsq(n, f, a, option)
y = fir_lsq(n, f, a, w, option)Legacy name: firls
Filter order. n is a nonnegative integer.
Normalized frequencies at which you want to take samples. The size of f must be even. f is a vector.
Specifies the amplitudes at each of the f frequencies. a is a vector of the same size as f.
Weight. w is a vector that is half the length of f.
Odd-symmetry filter to design. option is a string that accepts the following values:
Filter coefficients of order n. y is a real vector.
If f = [0.1, 0.2, 0.3, 0.4] and a = [1, 1, 0, 0], MathScript ignores the interval [0.2, 0.3] and attempts to implement a filter whose amplitude is 1 in [0.1, 0.2] and 0 in [0.3, 0.4].
N = 11; F = [0.1, 0.2, 0.3, 0.4]; A = [1, 1, 0, 0]; Y = fir_lsq(N, F, A)
