%SHANINFO Information on complex Shannon wavelet.
%
%   Complex Shannon Wavelet
%
%   Definition: a complex Shannon wavelet is
%           shan(x) = Fb^{0.5}*sinc(Fb*x)*exp(2*i*pi*Fc*x)
%   depending on two parameters:
%           Fb is a bandwidth parameter
%           Fc is a wavelet center frequency
%
%   The condition Fc > Fb/2 is sufficient to ensure that
%   zero is not in the frequency support interval.
