Difference in the depth of modulation

Okay, kiddo, let's talk about how radio signals work. You know how when you talk to someone on the phone, your voice travels through the air as sound waves and goes into the phone? Well, radio signals work kind of like that.

When someone sends out a radio signal, it also travels through the air as waves - just like sound waves, but at a much higher frequency that we can't hear. And just like sound waves, radio waves can be changed to send different kinds of information. This is called modulation.

One way to modulate a radio signal is by changing the depth of the signal. Depth of modulation just means how much the signal changes from its "normal" level. Think of it like turning up or down the volume on your voice when you talk.

So, if the signal has a high depth of modulation, it means it's changing a lot from its normal level. This can make it easier for us to understand the information being sent, but it also means the signal could interfere with other signals nearby.

On the other hand, if the signal has a low depth of modulation, it means it's not changing much from its normal level. This can make it harder for us to understand the information being sent, but it also means the signal is less likely to interfere with other signals nearby.

So, in summary, depth of modulation refers to how much a radio signal changes from its normal level, and it can affect how understandable the information being sent is and how much it interferes with other signals.
