Envelope follower for my vocoder...

[Kevin Peek]

Thanks to everyone for helping me out so far with my vocoder project.
I greatly appreciate it.

I am going to change the VCA to one of Jorgen's LM13600 designs.

However, many people suggested a simple diode rectifier for the env.
follower.

Should this be a half-wave or full-wave?
I thought that all full-wave rectifiers need a center-tapped transformer?

I have looked at env follower from Craig Anderton's book, DR. Q, the
polyfusion, etc.
I looked at some half wave rectifiers.

It seems they are just :   signal----diode-----cap to
ground------resistor-----cap to ground-----output

Any further explanation or suggestions for this?

Once again thank you all!!!
