Expert Solution

Step 1

SNR is referred to as the signal-to-noise ratio and is frequently stated in dB. The quantity of background noise relative to the main input signal is measured by the signal-to-noise ratio. To obtain effective output, it is essential to be able to discriminate between different output signals. Decibels are commonly used to indicate Signal-to-Noise Ratio. The output is better the greater the SNR value.
