In the figure we have a basic oscillator with inverters obtained from TTL, CMOS or other gates. The graph on the side allows to find the frequency depending on the resistor and the capacitor.
This circuit was obtained in an 1975 English publication. It is a voltage regulator circuit for...
In the figure we have an infrared receiver circuit using an operational 741. The circuit is an...
