Indicated on an 80's Radio Electronics, this circuit provides at its output a voltage that is the peak value of the input voltage. The supply voltage must be higher than the expected peak.
This circuit produces a signal at a frequency of 455 kHz, based on a ceramic resonator CSA455E, by...
This simple unijunction circuit is from a Radio Electronics from July 1963. It can be assembled with a...
Hughes suggests this circuit in a 1968 documentation. The circuit uses old transistors that can be...
