### What is Meant by the Signal to Noise Ratio?

In the communication system, determining the signal to noise ratio is an important process. Because the signals in the transmission line might get affected by the random noise. To minimise the noise in the transmission process, signal to noise ratio (SNR) plays an important role. SNR is used to calculate the strength of the signal. If the SNR ratio is high, the true signal can be easily detected from the noise signal. Thus, the signal to noise ratio formula is given by

Signal to Noise Ratio = Power of Signal/ Power of Background Noise

(or)

SNR = P(Signal)/P(Noise)
