Modified Frequency Modulation

Imagine playing with a toy car that has a remote control. When you use the remote control to make the car go forward or backward, you are sending a signal to the toy car that tells it what to do. In a similar way, when we send information through the airwaves to a radio or a device with a wireless connection, we also use signals.

One way of sending signals is through a technique called frequency modulation (FM). FM works by changing the pitch of the waves that carry the signal. Just like how pressing different keys on a piano makes different sounds, changing the pitch of the waves creates different signals.

Now let's talk about modified frequency modulation (MFM). It is a way of sending signals that uses a combination of changing the pitch of the waves (like in FM) and also changing the timing of when the waves start and stop. By doing this, MFM is able to fit more information into each signal, making it more efficient than just FM.

Think of it like packing a suitcase for a trip. With FM, you can only fit so much stuff in the suitcase because you're just stacking things on top of each other. But with MFM, you can use space more efficiently by strategically folding and arranging your clothes so that you can fit more in the suitcase.

So to sum it up, modified frequency modulation is a technique of sending signals that changes both the pitch of the waves and the timing of when they start and stop. This allows for more information to be sent in each signal, making it a more efficient way of transmitting data.
