Triaxial BNC connector, typically used on precision electrical measurement equipment. Triaxial cable, often referred to as triax for short, is a type of electrical cable similar to coaxial cable, but with the addition of an extra layer of insulation and a second conducting sheath.
A TRIAC (triode for alternating current; also bidirectional triode thyristor or bilateral triode thyristor [1]) is a three-terminal electronic component that conducts current in either direction when triggered. The term TRIAC is a genericised trademark.
Music television: A program where people can listen to music on their TV's. This is just like a radio station. News show: A television program depicting real, up-to-date events. Current Affairs: Broadcast journalism where the emphasis is on detailed analysis and discussion of a news story.
Also AM radio or AM. Used interchangeably with kilohertz (kHz) and medium wave. A modulation technique used in electronic communication where the amplitude (signal strength) of the wave is varied in proportion to that of the message signal. Developed in the early 1900s, this technique is most commonly used for transmitting an audio signal via a radio wave measured in kilohertz (kHz). See AM ...
0-10V dimmer In production lighting this system was replaced by analog multiplexed systems such as D54 and AMX192 , which themselves have been almost completely replaced by DMX512 . For dimmable fluorescent lamps (where it operates instead at 1–10 V, where 1 V is minimum and 0 V is off), the system is being replaced by DSI , which itself is ...
A typical SCR based light dimmer which dims the light through phase angle control. This unit is wired in series with the load. Diodes (D 2, D 3, D 4 and D 5) for a bridge which generates DC with much ripple. R and C form a circuit with a time constant, as the voltage increases from zero (at the start of every halfwave) C will charge up, when C ...
One example is the TRIAC, which is comparable to two thyristors connected back-to-back (in other words, reverse parallel), but on a single piece of silicon. Two LEDs can be paired this way, so that each protects the other from reverse voltage. A series string of such pairs can be connected to AC or DC power, with an appropriate resistor.
Analog television system by nation Analog color television encoding standards by nation. Every analog television system bar one began as a black-and-white system. Each country, faced with local political, technical, and economic issues, adopted a color television standard which was grafted onto an existing monochrome system such as CCIR System M, using gaps in the video spectrum (explained ...
