Modulation in Communication Systems

Front

Why is modulation necessary in communication systems?

Back

Modulation is needed to transmit low-frequency signals over long distances.

Front

What is one reason modulation is necessary in communication systems?

Back

To reduce the size of transmitting antennas.

Front

How does modulation benefit communication systems in terms of signal transmission?

Back

It allows multiplexing, which means sending multiple signals over one channel.

Front

What is another advantage of modulation in communication systems?

Back

It minimizes noise and interference.

Front

How does modulation relate to channel bandwidth?

Back

Modulation helps match the signal to the channel bandwidth.
