radio sets were made up of an RF (or "antenna") amplifier, a tuner, a preamp, and an amplifier, will recall the introduction of "FM receivers" which incorporated all the separate components into one unit, usually with another tuner for AM radio, ("RCA phono" or "BNC") inputs for phono, mike, tape, and "AUX", bass, treble, and balance knobs, low and high filters, "loudness" switches, and perhaps separate outputs for different loudspeaker impedances. There was usually a large knob for tuning (which affected several stages), and sometimes one for "fine" tuning. Much confusion can be avoided simply by consistently using "tuner" when referring to the (RF) tunable component within the receiver and "receiver" when referring to the entire apparatus (including the tuner hidden within it) which the user employs to receive the broadcast medium. The "TV set" can be regarded as a (sometimes) separate "output device".
781:"Convert ... over" makes no sense. The confusion about the meanings of "tuner" and "receiver" is a serious one, since there's no way to discuss what something does unless it can be identified first. As for the meanings of "analog" and "digital", they, too, are used differently in different contexts. The electro-magnetic phenomena which pass through space are inherently analog, like waves on the ocean, but the information they contain must be interpreted (after many earlier steps) as digital data before it can yield any "meaning". We must make clear to the reader exactly what occurs from the moment a broadcast signal meets an antenna until the time it produces images and sounds. It's almost impossible to get anywhere without block diagrams.
386:
receiver provides a signal appropriate for the human interface (e.g. low impedance power output for loudspeakers, else composite, component or digital signal for monitor, else encoded stream for computer-based software viewer). Back to the subject: this specific element of a television (the ATSC tuner) is unambiguously a tuner (and not a receiver), just as it has been so named by the industry. And furthermore, this discussion of "common lingo" screams *original research*. It's certainly not a technical fact backed up by any reference. It should be removed from the "Technical
Discussion" section unless a credible citation can be found.

305:(more commonly called the "All Channel Receiver Act") in the 1960's, if not before, the term "receiver" means a full-blown TV set which both selects ('tunes') the channel and displays ('receives') the picture. A "tuner" is the channel-selecting component of a receiver or other device (such as a VCR or digital-to-analog converter).--
371:
the term receiver here should solely be used with eh qualification that a "receiver" is one of many devices using a ATSC tuner - the great majority of which are NOT receivers. To interchange the terms as done here with recent edits is no different than an article on motors stating that cars are motors!

RBBrittain and the rest who agree with the heading are correct. TVs can and do sometimes contain several tuners, but the unit is just one "receiver." You would call the entire TV a receiver. You might also call a tuner/DVR combo a receiver. You could even call a USB TV tuner a receiver, because a

I strongly disagree with the heading; "receiver" is correct, not "tuner". A receiver is comprised of several components, only one of which is the tuner. The tuner is the part which can be manipulated to focus in on a frequency. Those of us who have been around long enough to remember when hi-fi FM

Receiver is not the correct term anyway for the objective reason that several of the devices are not receivers, which are generally and vy all traditional a/v definitions defined by having amplification. A PC tuner card has no amplification, many set top TV tuners have no amplification. All use of

So, does this device convert the digital signals over the analog? I was reading this under the impression this is the type of tuner to buy for when they switch the analog TV signals off, and have digital takeover. This article references the shutdown a few times, but always talks about converting
315:
The receiver is receiving the VHF/UHF EM wave, processing it, and outputting an audio/video signal. The tuner is just one component in the box. Your perspective seems to be oriented towards what is the common lingo. And I am not disagreeing with what you said. What I am suggesting is what the

Analog to digital conversion, sometimes called ADC or A to D refers to a technology in which an analog signal is converted into a digital signal. In the context of an ATSC tuner, an analog TV broadcast that is broadcasted over the air is received by the ATSC tuner and converted from its original

I went to the non-existent "HD tuner" article and got redirected here. My understanding is that having an ATSC tuner does not necessarily mean that your TV can accept an HD signal--that you need an "HDTV tuner." True?

common lingo should be. If you take a common stereo AV receiver and strip out many of its components but leave the tuner, then you have what is commonly called a tuner.

An ATSC signal can be HD, depending upon what is being broadcast. An ATSC tuner must accept an HD signal, although it may output a standard definition video as current

Also found two Sanyo TVs, 27" and 32" flats, that are listed as SDTV (and have both NSTC and ATSC tuners). Sad that my 20" Sanyo from 1992 is considered small now. -

What makes you say that? I see little or no duplication of content. Perhaps digital tuner should be merged with analog tuner, since most tuners are becoming digital.
