function newsig = normalize(origsig, fftlength, numbits)
% newsig = normalize(originalsignal, fftlength, numberbits)
%
% NORMALIZE takes in a signal and normalizes its power spectrum
% to a 0 db maximum. This is done by taking into account the 
% FFT transform length that will be used and the bits per sample.

newsig=origsig./(fftlength.*(2.^(numbits-1)));
