Repairing radios was easier when radios were simple. There were typically two strategies. You could use a signal tracer (an amplifier) to listen at the volume control. If you heard something, the ...

A signal injector is a very useful and quick troubleshooting tool for signal tracing in a circuit. Using it can quickly determine the faulty stage of a radio receiver, for example. The signal injector ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

A transportable unit was built for the testing of LF and MF receivers. It provides more than 60 dB of screening from the effects of external fields and includes a simple signal-injection system that ...

The circuit was designed to produce a simple test circuit for monitoring, tracing and locating any fault or defect in a radio or analog equipment and other electronic circuitry. Single Pole Double ...
