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.
The integrated circuit used in this amplifier is not common today. The power can be between 4 and...
This circuit was obtained from a 1997 publication. It is an alarm that has a lock and a bistable...
We found this circuit in a 1991 publication. What it does is to amplify a signal with unit gain...
