Analogue TV -
Analog waves are continuous when being transmitted
This signal varies in amplitude, depending on the information that it contains
This analogue signal is transmitted on a particular radio frequency, from the television station’s transmitting antenna over the air to the receiving antenna connected to the TV set.
So the wave can be interrupted by buildings, walls and other objects.
So the quality will vary depending on the wave connection strengths.
There are only 5 analogue channels -
It is easy for the radio waves to be interrupted or obstructed, meaning that they will not reach the TV properly
You can only receive the TV in the radius that the TV antenna will reach. The further away from the antenna you are, the worse the signal is.
It is common for analogue TVs to have worse picture quality, grainy backgrounds, snowy images and poor/static sound, because the TV's antenna is not picking up all of the radio waves.
