Concept explainers

Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.

Question

100%

The noise factor of a communication system is given as 12.54.

What will be the value of the noise figure of the system?

Expert Solution

Step 1

The noise factor (F) is a very important parameter which is used to measure how a signal degrades when it passes through a communication system. It is defined as the ratio of the signal to noise ratio at the input of the system to the signal to noise ratio at the output of the system.

In this case, the value of the noise factor for the communication system is given as

Step 2

The noise figure (NF) can be obtained from the noise factor (F) using the following relation:
