Hi guys,

I want to know how to calculate from a pcm file the following things...

1. Rms value of a signal when it is having single frequency and also multiple frequencies .
2. Rms value of harmonic components of a signal when it is having single frequency and also multiple frequencies .
3 Rms value of noise..

By using above values i want to calculate SNR, THD , THD+N.

Thanks in Advance
