This circuit was found in a 90’s Electronic Engineering. The signal is sinusoidal with the frequency given by the non-value components that form the resonant network.
The capacitance shown at the output of this circuit is given by the relationship between R1 and...
The circuits shown below consist of diode protections against accidental polarity reversal in the supply...
This two-transistor circuit was found in the January 1994 issue of Electronics Now magazine....
