Found in a 1965 General Electric datasheet, this low frequency circuit divides the frequency of a 20 kHz signal by 10, thus obtaining a 200 Hz signal.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
