Found in a 1968 American documentation, this circuit generates sawtooth signals whose rise and fall times are determined by C1 and C2. Transistors support modern equivalents.
The circuit shown is from an old European publication. In it we have the way to activate a relay...
We found this circuit in a European publication from the 1990s. Transistors are still common types...
This circuit was found in an American documentation and can be added to common amplifiers of any...
