Question

signal to noise setio is equal to the reciprocal​

Answer 1

Explanation:

Formulas for Calculating Signal to Noise Ratio FSD (or SQRT) Method. For decades now, HORIBA Scientific has defined the SNR as the difference of Peak signal minus Background signal, divided by the square root of the Background signal.

Answer 2

Answer:

Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
