This time base circuit for the oscilloscope was obtained from an Electronics Now from the 90s. The circuit is intended to control the cathode ray tube of old oscilloscopes.
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...
