This circuit uses NOR ports to generate signals up to 10 MHz, depending on the crystal. The supply can be done with voltages from 5 to 15 V and the signal generated is rectangular.
This circuit can be used as a control shield for microcontrollers of all types. The supply is made...
The load used in this experimental circuit is a small incandescent lamp but it can be replaced by...
Found in an American documentation from 1992, this circuit for medium and short waves uses a CI of...
