%
%     usage:  [b, a, mu] = shelving_HP(fc, fs, g)
%     
%           b = Two column vector, numerator coefficients
%           a = Two column vector, denominator coefficients
%          fc = Scalar, cutoff frequency (in Hz)
%          fs = Scalar, sampling frequency (in Hz)
%           g = Scalar, boost/cut gain (in dB)
%          mu = Scalar, high-pass output scaling factor
