The pentagrid converter is a type of radio receiving valve (vacuum tube) with five grids used as the frequency mixer stage of a superheterodyne radio receiver. The pentagrid was part of a line of development of valves that were able to take an incoming RF signal and change its frequency to a fixed intermediate frequency , which was then ...

The term radio receiver is understood in this article to mean any device which is intended to receive a radio signal in order to generate useful information from the signal, most notably a recreation of the so-called baseband signal (such as audio) which modulated the radio signal at the time of transmission in a communications or broadcast system.
A direct-conversion receiver (DCR), also known as a homodyne, synchrodyne, zero intermediate frequency or zero-IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is identical to, or very close to the carrier frequency of the intended signal.
1 Mini-DIN 4-pin, 1 Mini-DIN 7-pin, 1 Mini-VGA, 2 BNC, 2 RCA connectors, 8-pin DIN, [4] SCART 21-pin: S-VHS, some laptop computers, analog broadcast video, 1980-1990s home computers including the Commodore 64, C128 and Atari 8-bit computers: The 4-pin mini-DIN that is most common in consumer products today debuted in JVC's 1987 S-VHS. The 7-pin ...
In the simplest type of radio receiver, called a tuned radio frequency (TRF) receiver, the three functions above are performed consecutively: [9] (1) the mix of radio signals from the antenna is filtered to extract the signal of the desired transmitter; (2) this oscillating voltage is sent through a radio frequency (RF) amplifier to increase ...
The introduction of AC/DC circuitry allowed a single model to be used on either AC or DC mains as a selling point, [2] and some such models added "Universal" to their name [3] (such sets usually had user-settable voltage tapping arrangements to cater for the wide range of voltages). [4] The first ever AC/DC design of radio was the All American ...
Doubling the height of the single DIN, a video display or touchscreen can be fitted to support manufacturer GUIs, Android Auto, Huawei HiCar and/or Apple CarPlay. [3] Double DIN is also written as 2 DIN and double din. For both single and double DIN units, ISO 10487 is the connectors standard for connecting the head unit to the car's electrical ...
