Answer:
SNR which stand for signal to noise ratio is a ratio that is calculated to compare the disired signal level and background noise level
Explanation:
SNR which stand for signal to noise ratio is a ratio that is calculated to compare the disired signal level and background noise level. It is expressed in db i.e. decibel. and ratio of 1:1 shows more signal level than noise.
generally signal with 20 db is considered as good SNR value while 18 db around SNR is good for data.
