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. 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 ...

4. Cable television - Wikipedia

   en.wikipedia.org/wiki/Cable_television

   Broadband internet access is achieved over coaxial cable by using cable modems to convert the network data into a type of digital signal that can be transferred over coaxial cable. One problem with some cable systems is the older amplifiers placed along the cable routes are unidirectional thus in order to allow for uploading of data the ...

   8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.

6. Intermediate-frequency amplifier - Wikipedia

   en.wikipedia.org/wiki/Intermediate-frequency...

   IF amplifiers in heterodyne receivers apply gain in a frequency band between the input radio frequency and output audio frequency or video frequency, often following one stage of RF amplifier. This allows most of the gain in the form of a fixed-frequency amplifier, simplifying tuning. Compare to its predecessor, the tuned RF receiver.

7. Tuner (radio) - Wikipedia

   en.wikipedia.org/wiki/Tuner_(radio)

   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 a picture. [29] [30] [31] A TV tuner must filter out unwanted signals and have a high signal-to-noise ratio. [32]
