Thatīs exactly the way to go, though I wouldnīt use an electrolytic
capacitor. A suitable buffer is described in oscope-1.7.tar.gz by Tim
Witham (twitham_AT_quiknet.com).
The signal level, at least after the first amp stages, shouldnīt exceed
some volts.
Iīve read this thread from the beginning, but as I know next to nothing
about DSP coding, I didnīt jump in. But now as it comes to hardware,
which is my domain, I want to offer my help. Please feel free to contact
me.
