I used the Fast PWM mode, 31kHz and a sinewave 600Hz modulation frequency, sampled 8 to 32 times per cycle. IOW, I changed the PWM pulse width 8 to 32 times per cycle of the modulation sine wave. The modulation sine wave sampling rate seemed to make little difference in the FFT of the output as displayed on a TDS 2014.
I'd be interested to see what a Tek 7L5 would think of it. In my experience, analog and digital (sampled) SAs have surprisingly different views of the world. _______________________________________________ AVR-GCC-list mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
