In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
Their TV was mounted high on the wall at an angle, pointed down. "Every post I came across would make me stare at my TV and think about how hard I would get roasted. So I had to do something about ...
Lack of 3-phase electric system connected by star. If neutral breaks off, small-power appliances will be destroyed by overvoltage. Electronic and electrical devices are designed to operate at a certain maximum supply voltage, and considerable damage can be caused by voltage that is higher than that for which the devices are rated.
For example, a large color TV CRT may require 20 to 50 kV with a horizontal scan rate of 15.734 kHz for NTSC devices and 15.625 kHz for PAL devices. Unlike a power (or "mains") transformer, which uses an alternating current of 50 or 60 hertz , a flyback transformer typically operates with switched currents at much higher frequencies in the ...
This time, check the actual TV's measurements, then make sure it'll fit the space where you intend to hang it. Most 85-inch TVs stretch about 75 inches wide and 43 inches high.
LNA-100 Boost Antenna Amplifier. If you’re looking for an antenna amplifier that's easy to set up and minimizes wires in your house, the Winegard LNA-100 Boost is an ideal choice.
The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. [ 1 ]
Furthermore, 43% of retirees believe their benefits will be cut in the future, while 47% of nonretired adults worry that Social Security won't be able to pay them a benefit at all once they retire.
