Signal-to-noise ratio (SNR or S/N) is a measure that compares the level of a desired signal (wanted information) to the level of background noise (unwanted information), often measured in decibels. Using the logarithmic decibel scale, the formula to calculate SNR is SNR = 10 log 10(Power_of_signal / Power_of_noise). Calculate a signal to noise ratio in decibels. Assume the values for power are positive. Report any errors in input.
