This signal injector and tracer (follower) was found in an old American documentation. The transistors can be general use and power is made with one or two common cells.
This circuit appears elsewhere on this site using the most diverse transistors. This version is...
Frequency in this oscillator is controlled by a crystal. Any 1 MHz to 15 MHz can be used. The JFET can...
This was one of the National Semiconductor clock modules very popular in the 70s and 80s. In the...
