How can we reduce noise in SNR?

Reducing Signal to Noise Ratio (SNR)

The SNR can be improved by either increasing the overall amplitude of the signal before the noise is introduced into it, or by reducing the amplitude of the noise. A common source of noise in many applications is the measurement device.

What is signal-to-noise ratio how it can be improved?

A signal-to-noise ratio over 0 dB indicates that the signal level is greater than the noise level. The higher the ratio, the better the signal quality. For example, a Wi-Fi signal with S/N of 40 dB will deliver better network services than a signal with S/N of 20 dB.
