Hey guys,
I'm going to implement a matched filter, but faced a problem with the basic idea behind that. When we apply a signal to the input of the matched filter, say a sine wave, and assuming we have knowledge about the amount of the noise at the input, we can easily calculate SNR of the input signal. However, when this signal passes through the matched filter, the output is just one number (amplitude of the original signal), so how the output SNR would be defined for this kind of filters?
Thanks!
