Question

In T.V. broadcasting both pictures and sound are transmitted simultaneously. Explain.

Answer 1

Explanation:

1. Amplitude modulation is the initial sort of modulation that is used to broadcast sound, as we all know. The process of turning sideband or data into radio waves by adding information to an electronic signal or optical carrier signal is known as modulation.
2. Let's look at the figure to see how the signals are transmitted.
3. As seen in the above diagram, audio and video are transferred as analog signals across a radio carrier wave.

1. As is well knowledge, modulation creates the modulated signal, which takes into account the transmission channel's properties. This refers to the messaging transfer onto the available high-frequency radio channel.
2. The frequency-modulated audio signal is therefore necessary for both the television's audio and video, whereas amplitude-modulated signals are necessary for the television's audio.
