Re: Dspic for FTT
Each of the 2 accelerometer x 3 (xyz) channels will have an output:
-signal: energy measurement over a bandwidth of at least 7kHz. Ideally 10kHz. It will contain 2 to 3 orders of the fundamental.
- The harmonic 1 (expressed in dB)
-we expect a sampling frequency of the order of 20kHz to 30kHz
so it's for me to chose the dspic (or pic32 ??) to get real time FFT of this 6 signal, I can use 2 dspic .
and get the first harmonic.
