I put a plain-jane label on the precision (and/or possible high speed) rectifier circuit after the log amp. Call it what ever you like... > Yes, there is some very intentional audio spectral focus to avoid > being sensitive to CTCSS and DCS components, and to emphasize where > the noise spectrum is best for voting, but it is not relying on the > high frequency component alone. My use of the high frequency label is/was meant to be generic. The larger picture is where the "audio spectral focus" is intended to be placed and what other components to some major or less degree effect the operational performance. skipp
