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 three-transistor amplifier uses a JFET at the input to increase the input impedance. The...
This two-transistor MW radio was found in a publication from 1958. It uses one of the oldest type...
This simple circuit was suggested by the Electronics Handbook Volume XIII 1993. LED D1 emits light for...
