We show an oscillator that produces rectangular TTL signals based on inverters. Inverters can also be designed with standard NOR or NAND gates. The circuit must be powered by 5 V.
This circuit regulates the output voltage of a 78xx according to the light incident on the sensor....
Frequency divisions up to 18,384 can be performed with the basic configuration of a 4020 as shown...
The frequency of the tone produced by this oscillator depends on the amount of light falling onto...
