How do you identify a signal noise?

Therefore, to ascertain the signal to noise ratio, one must find the quantifiable difference between the desired signal strength and the unwanted noise by subtracting the noise value from the signal strength value.

How can I improve my 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.
