: The FIR filter design involves selecting a window function and a filter length. Using the Hamming window, we can design a FIR filter with a cutoff frequency of 0.2π:

The impulse response is then:

E(f) = e^-2π^2f^2σ^2

X(f) = ∫[−T/2, T/2] e^-j2πftdt

H(z) = 1 / (1 - 0.5z^-1) = 1 + 0.5z^-1 + 0.25z^-2 + ... : The FIR filter design involves selecting a

h[n] = Z^-1 H(z)

X(f) = e^-π^2f^2σ^2
