I need to know in what format are the data from a sigma-delta output.
I know that after modulator data is a 1bit stream (PWM) with high freq. After that is a decimator with a low-pass FIR filter. I want to know haw to make this filter and in what order to introduce data. The code from FIR output filter is binary or PWM ???
I need help from someone who worked with all this stuff.
