This circuit is from a Radio Electronics from April 1964. The circuit uses power transistors of the time, which must be mounted on a good heat radiator. Modern equivalents can be used.
This circuit is suggested by RCA and is based on a dedicated integrated circuit that is the...
This circuit was found in a Popular Electronics from the 90's. The frequencies depend on the...
We show in the figure how to implement the No-AND or NAND logic function using a general-purpose transistor....
