Found in a 1964 Electronic Design, this circuit shows how to modulate a signal with a dynamic low impedance microphone. The circuit operates in the FM range (88 to 108 MHz).
I found this circuit in an old document from 1981. The circuit can be implemented today with the...
The circuit presented is a 10 MHz oscillator with crystal, which already has several splitters for...
This two-transistor amplifier stage was obtained from the Encyclopedia of Electronic Circuits...
