Analizator de spectru audio cu PIC

Recommended Posts

Buna , as dorii sa stiu cum pot utiliza ADC-ul unui PIC pentru a putea afisa (ex . pe un lcd) un spectru audio pe mai multe trepte (ex. 100,200,400,1k,6k...16k Hz).Nu stiu cum sa implementez FFT (Fast Fourier Transform).Detin un 18F4520 care ar fii destul de rapid pentru a face calcule pentru 10 benzi .
