This circuit amplifies signals from 0.5 Hz to 300 kHz. We found it in an old documentation. Equivalent transistors may be used. The gain is 20 dB.
This RF circuit measures transmission power from 0.25 W to 10 W. The maximum frequency depends on...
This traditional 555 touch bistable configuration has already been explored in projects on this...
This circuit was found in a RCA documentation from 1977. The integrated circuit is uncommon today. It is...
