Analogtelevision encodes picture information as an analog signal, that is, by varying the voltages and/or frequencies of the signal. All systems preceding digital television can be considered analog.

Conventional Analog Television - An Introduction (http://www.ee.washington.edu/conselec/CE/kuhn/ntsc/95x4.htm)
The first practical TV transmissione were performed by John Logie Baird in 1926 (30 lines/frame, 5 frames/s).
In 1965 Europe failed to agree on one colour TV broadcast system: France went SECAM, eastern Europe decided on "a variety of SECAM", while most of the remainder of Europe decided to use PAL.
SECAM colour TV was insensitive to this flutter, however since SECAM uses FM on its colour subcarrier, the frequency spectrum became complicated and the risk of intermodulation, causing interference patterns in the picture, was large.
About AnalogTV Television picture and sound information is encoded as an analogsignal, that is, by varying the amplitude and frequencies of the signal.
Analog transmission of television programming will cease to operate in the United States in 2009, requiring all television sets to have a digital tuner to receive television broadcasts.
Because SECAM is incompatible with other TV systems, it was adopted by many former Communist countries to prevent their people from seeing and being influenced by TV programming from Western countries.
