Tuner (radio) A tuner is a subsystem that receives radio frequency (RF) transmissions, such as FM broadcasting, and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output. Broadcast FM / AM transmissions usually ...
A TV tuner card is a kind of television tuner that allows television signals to be received by a computer. Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk much like the digital video recorder (DVR) does. The interfaces for TV tuner cards are most commonly either PCI bus expansion ...
Set-top box. A set-top box ( STB ), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [ 1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into content in a form that can then be displayed on the ...
Radio Data System ( RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU ...
Software-defined radio ( SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators / demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [ 1] While the concept of SDR is not new, the ...
Auto-Tune. Auto-Tune is audio processor software released on September 19, 1997 by the American company Antares Audio Technologies. [ 1][ 4] It uses a proprietary device to measure and correct pitch in music. [ 5] It operates on different principles from the vocoder or talk box and produces different results. [ 6]
An antenna tuner, a matchbox, transmatch, antenna tuning unit ( ATU ), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...
