32.
If Eb, the energy per bit of a binary digital signal is 10-6 watt sec. and the one sided power spectral density of the white noise N0 = 10-5 W/Hz, then the output SNR of the matched filter is
Answer: Option
Explanation:
O/P SNR = 10 log10 [2 x 10-6 x 10-5].

SNR = 2Eb/No.
And then 10log(SNR).
The answer 13db is only valid if the noise and signal energies/power are swapped. Then you get 13db otherwise you get -7dB.

O/p SNR = 10log (N0/bit power).

Shouldn't it be 10log10 (2*10^-5/10^-6)?
