Signal to noise ratio of a signal can be estimated using mean-to-standard deviation ratio (M/SD) for digital signals. Initially, by observing the values of M/SD for a signal with known noise level a threshold can be obtained. However when I am trying to compare the M/SD signal with a threshold using if statement, this is not working:
The threshold value has been observed from the plots of M/SD for signals with and without noise. What can be the possible reason for the statement not getting executed? Is it that i am trying to compare a stream with a number??
