Found in American documentation from the 90s, this circuit uses TTL technology and is therefore compatible with microcontroller drives. The circuit must be powered by a 5V power source.
The oscillator shown in the figure can generate signals up to 500 kHz and has good stability. Coil...
This circuit uses a voltage comparator and can produce signals up to 20 MHz. The resistors R are...
This type of amplifier can be found in many other points in this section. This is from a 70s...
