Based on CMOS logic this short-circuit locator circuit uses the ear's ability to detect small changes in pitch, which are caused by variations in millivolts in a track under analysis.
We found this circuit in the March 1992 issue of Radio Electronics magazine. The circuit has a...
The circuit presented may use any general purpose transistor. The indicator is an LED and...
This unusual audio amplifier configuration was obtained in a 1974 documentation. The PNP...
