Hi Markus, Interesting! This could be easily done of course. If it is possible to modify your chirped hell software to drive such a PA in SpecLab, i would build a separate LF/VLF PA. It's time to tra

Two stereo outputs, could be digitised and the resulting values used to  access a lookup table that contains the pulse width.   It may just about be possible that PIC could be fast enough;  a DSPPIC

Hello Markus and Stefan, Phew, that sounds interesting.. the question is how to convert the output of the inverse FFT (with the 'analog' chirped Hell signal) into your described digital (square wave)

Dear Stefan, thanks very much for sharing this very useful design! Just in case you would like to extend this to linear modulation: The H-bridge topology naturally lends itself to the Outphasing tech
