2 Transistors Signal Generator For Signal Tracing

Signal tracing is a method to find failure section of electronic circuit. This method is very common in troubleshooting audio electronics, since the tool for injection and monitoring will be very simple and cheap. The tracing method is done by injecting a signal source at one point and monitoring the response at other point, where the signal is assumed to […]

Audio Signal Injector and Tracer in One Circuit

If you are building or troubleshooting audio circuits, both audio signal injector and audio tracer is important tools. tracing audio signal means tapping a signal at certain point, and check if the signal is exist.  Here is the schematic diagram of the  signal injector/tracer circuit: Tracing an audio signal can be done using an audio amplifier, but using a handheld […]
