This oscillator provides a 1 MHz rectangular signal determined by the capacitors used. The circuit must be powered by a voltage of 5 V. The maximum frequency depends on the logic used.
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...
