This circuit is from 1964 documentation but can be easily implemented based on current components. Input waveforms and detection are shown next to the diagram.
This common configuration is one of many that can be found in this section using the 555. The...
The load on this amplifier is 8-ohm. We found the circuit in a 1972 Motorola amplifier manual. The...
This circuit is from an old Motorola manual (1999) using an integrated circuit that is not very...
