Fixed emulator discrepancy

In the frontend hardware after the sliding window applied in the peak-finder block the output
of each filter is saturated at 12bits. Then, the even and odd outputs are compared.

In the emulator the saturation was not checked and the odd and even amplitudes were compared at 18bits.
This PR fixes the problem.
