What is Noise To Signal Ratio?

The noise to signal ratio (NSR) is a measure used in science and engineering to quantify how much a signal has been corrupted by noise. It is the ratio of the power of noise to the power of the signal. A lower NSR indicates a cleaner signal, while a higher NSR indicates a noisier signal. This metric is crucial in fields such as telecommunications, audio engineering, and data transmission, where maintaining the integrity of the signal is essential for accurate data interpretation and communication.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ R = \frac{0.5}{10} = 0.05 \]

The Noise to Signal Ratio is 0.05.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ R = \frac{1}{20} = 0.05 \]

The Noise to Signal Ratio is 0.05.
