Analog television or analogue television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by rapid variations of either the amplitude, frequency or phase of the signal.
Analog signals vary over a continuous range of possible values which means that electronic noise and interference becomes reproduced by the receiver. So with analog, a moderately weak signal becomes snowy and subject to interference. In contrast, a moderately weak digital signal and a very strong digital signal transmit equal picture quality. Analog television may be wireless or can be distributed over a cable network using cable converters.
All broadcast television systems preceding digital transmission of digital television (DTV) used analog signals.
Analog television around the world has been in the process of shutting down since the late 2000s.
The earliest systems were mechanical television systems which used spinning disks with patterns of holes punched into the disc to scan an image. A similar disk reconstructed the image at the receiver. Synchronization of the receiver disc rotation was handled through sync pulses broadcast with the image information. However these mechanical systems were slow, the images were dim and flickered severely, and the image resolution very low. Camera systems used similar spinning discs and required intensely bright illumination of the subject for the light detector to work.

"Analog"
through the coolest haze
of this dreamlike maze
it has begun
and all i wanted you near
with these wounds i bled
a perfect tone of red in isolation
through the swollen eyes of the dying
and my waking dreams we're all dying
to become what we swore we never would
now i watch and mourn in bloom
you take the way you know
i'll take the road unknown
and meet you there
at the end of time
we are frequency
we are tragedy
we are the love
we need to keep us here
we are the dying we are the lonely ones
we are the waiting forever faithful
when i see you on the other side
i will not be the same
as i was when i was yours
how i wanted you near!!!
we are the dying we are the lonely ones
we are the waiting forever faithful
when i see you on the other side
i will not be the same
as i was when i was yours
