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. Its input is a baseband signal, which is used to modulate a radio ...
Direct-conversion receiver. A direct-conversion receiver (DCR), also known as homodyne, synchrodyne, 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.
Frequency synthesizer. A frequency synthesizer is an electronic circuit that generates a range of frequencies from a single reference frequency. Frequency synthesizers are used in devices such as radio receivers, televisions, mobile telephones, radiotelephones, walkie-talkies, CB radios, cable television converter boxes, satellite receivers ...
IQ imbalance. IQ imbalance is a performance-limiting issue in the design of a class of radio receivers known as direct conversion receivers. [a] These translate the received radio frequency (RF, or pass-band) signal directly from the carrier frequency to baseband using a single mixing stage. [b]
An RF modulator allows the use of a television as a monitor. Lowercase letters are displayed as small caps , rather than separate glyphs. TI BASIC , an ANSI -compliant BASIC interpreter based on Dartmouth BASIC , is built-in and includes support for graphics, sound, and file system access.
The RF Switch/modulator is for older televisions predating composite audio/video ports. It is identical to and compatible with earlier Nintendo RF modulators. It has the Nintendo 64 RF modulator cased in GameCube packaging, and its RF switch is the same as the original Nintendo Entertainment System and Super NES.
Product detector. A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a local oscillator, hence the name. A product detector is a frequency mixer.
Constant binary 1 and 0 levels are shown, as well as transitions from 0 to 1, 1 to 0, 0 to 1 to 0, and 1 to 0 to 1. In telecommunications , an eye pattern , also known as an eye diagram , is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input ( y-axis ), while the data rate ...
