2. Analog television - Wikipedia

   en.wikipedia.org/wiki/Analog_television

   In an analog television broadcast, the brightness, colors and sound are represented by amplitude, phase and frequency of an analog signal. Analog signals vary over a continuous range of possible values which means that electronic noise and interference may be introduced. Thus with analog, a moderately weak signal becomes snowy and subject to ...

3. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   Antenna amplifier for broadcasting service (here: TV broadcasting and FM sound broadcasting). In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead ...

4. Cable television - Wikipedia

   en.wikipedia.org/wiki/Cable_television

   Older analog television sets are cable ready and can receive the old analog cable without a set-top box. To receive digital cable channels on an analog television set, even unencrypted ones, requires a different type of box, a digital television adapter supplied by the cable company or purchased by the subscriber.

5. Amateur television - Wikipedia

   Analog big-dish satellite television receivers may be re-purposed for inexpensively receiving ATV in this band. Such receivers can decode FM television when an outdoor antenna is connected to the LNB input. Due to the low cost and ease of repurposing old analog satellite receivers, this is the most popular band for FM amateur TV.

6. Digital television transition - Wikipedia

   en.wikipedia.org/wiki/Digital_television_transition

   It is an involved process because the existing analogue television receivers owned by viewers cannot receive digital broadcasts; viewers must either purchase new digital TVs, or digital converter boxes which have a digital tuner and change the digital signal to an analog signal or some other form of a digital signal (i.e. HDMI) which can be ...

8. Output power of an analog TV transmitter - Wikipedia

   en.wikipedia.org/wiki/Output_power_of_an_analog...

   In analogue TV broadcasting, the video signal modulates a carrier by a kind of amplitude modulation (VSB modulation or C3F). The modulation polarity is negative. That means that the higher the level of the video signal the lower the power of the RF signal. The lowest possible modulating signal during the synchrone interval yields 100% of the ...

9. Analog passthrough - Wikipedia

   en.wikipedia.org/wiki/Analog_passthrough

   Any converter box converts the digital signal for the current digital sub-channel to an analog signal (at the reduced screen resolution of the analog standard), outputs that signal onto analog channel 3 or 4 (set by the user to avoid any conflict with local over-the-air channels) and sends that signal to the analog tuner on the TV. With a box ...
