It is desired to extract a constant signal s(n)= s from the noisy measured signal x(n)= s(n)+v(n)= s + v(n), where v(n) is zero-mean white Gaussian noise of variance ϭv2. For that purpose, the following IIR lowpass filter is used: H(z)= b/(1- az-1), H(ejω)= b/(1- a e-jω) , |H(ejω)|2 = b2/(1- 2a cos(ω) + a2) where a and b are arbitrary constants (0 < a < 1). Estimate the value of the cut-off frequency ωc if a = 0.08.
