A system used to process electronic signals can handle volta

A system used to process electronic signals can handle volt-ages up to 5V without clipping. The amount of noise produced by the circuitry of the system is 1 millivolt (0.001 V). What is the SNR of this system in dB? In the Laboratory

Solution

Signal V_signal = 5Volts

noise, Vnoise = 0.001 Volts

SNR = V/V_noise = 5/0.001 = 5000

SNR in dB = 20 log₁₀(V_signal /V_noise) = 20 log 5000

                                                     = 73.98 = 74 dB
