Question

State whether given statement is true or false :

The type of communication system needed for a given signal depends on the band of frequencies.

• A. True
• B. False

Answer 1

The correct option is A True

Different types of communication system needed for different band frequencies.For eg

1. The frequency range of speech signal is $300Hz$ to $3100Hz$.

2. Speech signal requires a bandwidth of $2800Hz$.

3. To transmit music $20KHz$ bandwidth is required approximately because the high frequencies produced by the musical instruments.

4. The audible range of frequency extends from $20Hz$ to $20KHz$

so, we can say that the type of communication system for a given signal depends on the band of frequencies.
