#### Problem Statement: Principles of Communications

**Noise Problem Solving**

The signal in a channel is measured to be 23 dB while noise in the same channel is measured to be 9 dB. The signal to noise ratio therefore is

A. 9/23

B. 23/9

C. 32 dB

D. 14 dB

#### Problem Answer:

The signal to noise ratio therefore is equal to **14 dB**.
