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 |
