Letter Frequency
This routine computes the fft of the input signal and removes power at the annual (or any specified frequency) by replacing the power at that frequency with the average of terms on both sides; this is done in the sine and cosine terms so as to average the power and the phase.

I started with Adam Wyatt's FROG program (on this website) but added to it and edited it beyond recognition. I did, however, subtract one useful feature: This program, as written, is SHG-FROG and GRENOUILLE only!! (Adam Wyatt's program was more general.)--> The program "prepFROG" takes a raw...
