A remote-control circuit controls other circuits through a relay or solid-state device, such as a motion-activated security light. A signaling circuit that provides an output that is a signal or ...

An article about how to design basic impedance matching networks using the pi and T-networks for improved selectivity.

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer ...

Remote Control and Signaling Circuits, Class 2 Using Class 2 circuits may eliminate shock or fire hazards, but only if you install them correctly.

The basic control circuit was simple, but too simple for safety — a projectile stuck in the barrel could leave a coil energized indefinitely, leading to damage.
