In the figure we have a good rectangular signals generator with several frequency bands. The circuit is based on old logic but can be implemented with modern equivalents.
With the circuit in the figure, it is possible to control the amount of heat generated by the...
The integrated circuit used in this regulator is from the 1980s, so it is difficult to obtain...
We found this conventional astable circuit in Ferranti's 1974 transistor manual. Transistors are...
