This is one of the many 7400 oscillators we have in our circuit bank. It is crystal controlled and must be powered with a voltage of 5 V.
This circuit is from a Radio Electronics from April 1972. The circuit uses power transistors of...
We found this simple circuit in a 1999 documentation. It converts low-intensity sinusoidal signals (a...
This very high voltage circuit was found in the 1990 special issue of Radio Electronics...
