Coherent Sampling Calculator

% Coherent sampling calculator for ADC testing
% Signal generator resolution in decimal places after MHz is
% considered to be 6 -- i.e. Resolution is 1 Hz
% See http://www.maxim-ic.com/app-notes/index.mvp/id/3190

% Finc: coherent input frequency of the test signal
% Fs: coherent sampling rate
% Fs: sampling rate
% Fin: input frequency of the test signal
% N: number of samples
function[Fsc,Finc] = csr(Fs,Fin,N)
