An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector ) is a circuit that performs demodulation , the inverse of modulation. A modem (from mod ulator– dem odulator), used in bidirectional communication, can perform both operations.
An RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a microcontroller which will provide data to the module which can be transmitted.
where =, being the sensitivity of the frequency modulator and being the amplitude of the modulating signal or baseband signal. In this equation, f ( τ ) {\displaystyle f(\tau )\,} is the instantaneous frequency of the oscillator and f Δ {\displaystyle f_{\Delta }\,} is the frequency deviation , which represents the maximum shift away from f c ...
A radio-frequency microelectromechanical system (RF MEMS) is a microelectromechanical system with electronic components comprising moving sub-millimeter-sized parts that provide radio-frequency (RF) functionality. [1] RF functionality can be implemented using a variety of RF technologies.
Bill Clinton is one proud grandpa!. On Monday, Nov. 25, the former President of the United States, 78, appeared on an episode of Live with Kelly and Mark and spoke about how he and the former ...
