What’s A Transformer?   A Transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in …

Also called inductive coupling. Coupling of two circuits by means of mutual inductance provided by a transformer.

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to …

What’s Transmission?   In telecommunications, Transmission is the process of sending and propagating an analog signal or digital signal using a wired, optical, or wireless electromagnetic transmission medium. Transmission technologies typically refer to physical layer protocol duties such as modulation, …

What Is a PCB Transmission Line?   A PCB Transmission Line is a type of interconnection used for moving signals from their transmitters to their receivers on a printed circuit board (PCB). A PCB transmission line is composed of two …

What’s A Transmitter?   In electronics and telecommunications, a Radio Transmitter or just Transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency (RF) alternating current (AC), which is applied to …

In laser cut stencils, Trapezoidal Apertures are created by distorting the beam on the laser, creating a draft in the aperture wall. Trapezoidal Apertures are effective if you plan on a long dwell time between printing of solder paste and …

What’s A TRIAC?   A TRIAC (Triode for Alternating Current) is a three terminal electronic component that conducts current in either direction when triggered. TRIACs are a subset of thyristors (analogous to a relay in that a small voltage and …

What’s Triangular Wave?   A Triangular Wave or Triangle Wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function. Like a square wave, the triangle wave contains only odd harmonics. However, …

Pulse used to initiate a circuit action.
