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 ...

This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

Every electrician has been there: You open a panel, and nothing is marked — or the markings are so outdated, you don’t have confidence in their accuracy. In some ...

The classic application for the circuit tracer involves finding which breaker supplies a given 120V load (Photo below). But circuit tracers aren't limited to 120V circuits or simply finding breakers.

The SureTrace™ Circuit Tracer Pro redefines what a circuit tracer can do. With numerical voltage readings, continuity testing, AC amperage readings, contactless tracing, and receptacle testing, it's ...

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 ...

Former Summit Director of Engineering Dennis Sloatman, now retired, encountered an annoying issue familiar to any of us who have home offices. Whenever he sent a job to his Brother laser printer, he ...

Amplifiers in cascode Configuration and their variations are generally used to overcome Miller Capacitance, improve the small signal gain and output impedance. Increasing number of transistors in ...
