Signal to Noise ratio for a hi-fi system is equal to ________

Signal to Noise ratio for a hi-fi system is equal to ________ Correct Answer 50 dB

Signal to Noise ratio compares signal power to noise power. It determines how much signal is present in a transmitted wave compared to presence of noise. It is generally expressed in decibels(dB). For a hi-fi system, it should be equal to 50dB.
