Hello, I'm looking for a project that may at one time been listed on this site:
Voice Activated Switch
The diagram was re-posted here:
I'm a beginner & not clear on all the parts needed.
There was a description & a link back here.
It began thus: "This circuit uses an MC2830 to form a voice activated switch ( VOX ). A traditional VOX circuit is unable to distinguish between voice and noise in the incoming signal. "
Thank you for your time.
