The modulator is then programmed to broadcast the signals on a certain frequency. That RF broadcast is then received by the connected TV. When the TV is tuned to the programmed channel, the video and audio signal of the source device is accessed. RF modulation can become difficult in a CATV system. High pass, low pass, and notch filters must be ...

The Sup 'R' Mod II kit has a small printed circuit board, an antenna switch, and a coaxial cable with a ferrite core and RCA connectors.Composite video is received by the circuit board through a short cable terminating in a Molex connector, which plugs into a header on the Apple II motherboard.
An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices.
A modulating retro-reflector (MRR) system combines an optical retro-reflector and an optical modulator to allow optical communications [1] and sometimes other functions such as programmable signage. [2] Free space optical communication technology has emerged in recent years as an attractive alternative to the conventional radio frequency (RF
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. [2] Based on Texas Instruments's own TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer. [3]
The IPO of the company on the NASDAQ stock market occurred on June 3, 1997 under the symbol RFMD. [9] At the time of the IPO, the company was a pioneer and leader in the use GaAs HBT process technology for commercial wireless applications, which had benefits in power efficiency, linearity, complexity and size, while also having expertise in older GaAs MESFET and silicon polar transistor ...
An American FM radio transmitter in Buffalo, NY at WEDG Edwin Howard Armstrong (1890–1954) was an American electrical engineer who invented wideband frequency modulation (FM) radio. [ 12 ] He patented the regenerative circuit in 1914, the superheterodyne receiver in 1918 and the super-regenerative circuit in 1922. [ 13 ]
