In electronics and radio , a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts , and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker . A tuner is also a standalone home audio product, component , or device called an AM/FM tuner or a stereo tuner that is part of a hi-fi or stereo system, or a TV tuner for television broadcasts. The verb tuning in radio contexts means adjusting the receiver to detect the desired radio signal carrier frequency that a particular radio station uses. Tuners were a major consumer electronics product in the 20th century but in practice are often integrated into other products in the modern day, such as stereo or AV receivers or portable radios .

68-765: A picture . A TV tuner must filter out unwanted signals and have a high signal-to-noise ratio. Television standards supported by TV tuners include PAL , NTSC , SECAM , ATSC , DVB-C , DVB-T , DVB-T2 , ISDB , DTMB , T-DMB , and open cable. VHF / UHF TV tuners are rarely found as a separate component, but are incorporated into television sets . Cable boxes , converter boxes and other set top boxes contain tuners for digital TV services, and send their output via SCART or other connector, or using an RF modulator (typically on channel 36 in Europe and channel 3/4 in North America) to TV receivers that do not natively support
102-531: A potentiometer supplying a variable voltage to varactor diodes in the local oscillator and tank circuits of front end tuner, for electronic tuning. Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator. This system shifts the radio frequency of interest to a fixed frequency so that it can be tuned with fixed-frequency band-pass filter . Still later, phase locked loop methods were used, with microprocessor control. The crystal radio receiver
136-433: A tank circuit which responds to one resonant frequency when combined with a detector , also known as a demodulator (diode D1 in the circuit). Stereophonic receivers include a decoder as well. Vacuum tubes made crystal sets obsolete in the 1920s due to their effective amplification. From the 1920s until the 1960s, most tuners used a vacuum tube -based design. Manufacturing shifted to solid state electronics in

#1732844094122408-668: A worldwide standard. FM broadcasting in stereo in the USA began in 1961 when authorized by the FCC . This led to greater demand for new radio stations and better technology in radios. The growth of hi-fi stereo systems and car radios in turn led to a boost in FM listening. FM surpassed AM radio in 1978. FM also doubled the number of stations, enabling specialized broadcasts for different genres of music. It also required consumers to purchase new equipment. The broadcast audio FM band ( 88 - 108 MHz in most countries)
442-512: Is 48.25 MHz - 855.25 MHz (E2-E69) , with a tuning frequency step size of 31.25, 50 or 62.5 kHz. Before the use of solid-state frequency synthesizers, covering the broad range of TV signal frequencies with a single tuned circuit and sufficient precision was uneconomic. Television channel frequencies were non-contiguous, with many non-broadcast services interleaved between VHF channels 6 and 7 in North America, for example. Instead, TV tuners of
476-580: Is around 100 times higher in frequency than the AM band and provides enough space for a bandwidth of 50 kHz. This bandwidth is sufficient to transmit both stereo channels with almost the full hearing range . The Post–World War II economic expansion in the US led to the growth of hi-fi products, increasingly seen as high tech hardware , with requisite jargon , and separated into premium quality components with high-class aesthetics and marketing. The 1970s and 80s were

Tuners may be monophonic or stereophonic , and generally output left and right channels of sound. Tuners generally include a tuning knob or keypad to adjust the frequency , i.e.
578-479: Is known as one of the first FM tuners precise enough to tune into a weaker station broadcast on the same frequency as another stronger signal. As a result of circuit miniaturization , tuners began to be integrated with other products such as amplifiers and preamps , and other digital electronics , and marketed as AV or stereo receivers for home theater or hi-fi systems. The Japanese development of silicon transistor technology led to popular radio products in
612-445: Is the simplest kind of radio receiver or tuner, and was the basis for the first commercially successful type of radio product design. Inexpensive and reliable, it was sold in millions of units and became popular in kits used by hobbyists, and was a major factor in the popularity of radio broadcasting around 1920. The crystal radio consists of a antenna , a variable inductor and a variable capacitor connected in parallel. This creates
646-519: The 1960s, but this didn't always result in improved sound quality compared to the older tube tuners. The radiogram , which combined a gramophone with a radio, was a predecessor of the hi-fi tuner. The transistor was invented in 1947 and largely replaced tubes. The MOSFET was used because it is capable of handling larger inputs than bipolar transistors . Starting in the 1960s, Japanese transistor radios , which were cheaper despite their crudeness compared to American designs, began to outcompete
680-587: The 1980s such as the boombox and the Sony Walkman . Although integrated hi-fi stereo systems and AV or stereo receivers contain integrated tuners, separate components are sometimes preferred for higher quality. Separating amplification also often increases overall performance. A television tuner or TV tuner, also called a TV receiver, is a component or subsystem that converts analog television or digital television transmissions into audio and video signals which can be further processed to produce sound and
714-514: The American products in the portable radio market. Eventually, after switching from germanium to silicon transistors, the Japanese consumer electronics companies achieved a dominant market position. Heathkit , an American company which had supplied popular kits for electronic devices since the 1940s, went out of business in 1980. FM broadcasting originated in the United States and was adopted as

850-517: The era incorporated multiple sets of tuned circuits for the main signal path and local oscillator circuit. These "turret" tuners mechanically switched the receiving circuits by rotating a knob to select the desired channel. Channels were presented in fixed sequence, with no means to skip channels unused in a particular area. When UHF TV broadcasting was made available, often two complete separate tuner stages were used, with separate tuning knobs for selection of VHF band and UHF band channels. To allow for
