Bandlimited filters. Effect of bandwidth limits on Walsh filters. (a) Bandlimited reconstructions of \(\mathrm{WAMF}_{0,3}^{(1)}\) modulation envelope as a function of first-order Butterworth filter parameter \(f_{c}/f_{s}\). (b) Red: Closeup of circled region in (a); Black ideal square profile. (c) Filter-transfer functions for profiles in (a).
