Based on a PLL 567, this circuit serves as a receiver for the CB9574E circuit. S tuning is done in R1 and it is used for frequency modulated signals.
This circuit was found in a 1980s documentation for amateur radio. The circuit makes use of...
A positive transition in the trigger makes the outputs change state and remain so for the time...
This traditional transistor source uses only two transistors found in a 1998 documentation. The...
