Determine the matched filter response h(t) for signal s(t) shown below...
A matched filter is used to increase the signal-to-noise ratio (S/N) at the receiver end by correlating the filter impulse response with the known input signal.
i.e. provided h(t) = Si*(T - t), where Signal Si(t) exists for 0 ≤ t ≤ T, the filter is said to be a matched filter.
i.e. h(t) = (SiR(T - t) + jSiImg (T - t))*
⇒ h(t) = (SiR(T - t) – jSiImg(T - t))
Where, SiR = Real part of Si(t)
And SiImg = Imaginary part of Si(t).
Calculation:
Given, Si(t) as shown;
So the real part of the filter impuse response must be –ve of the shifted part shown below,
And the imaginary part must be,
- [SiImg (T - t)] will be,
So, Option (4) is Correct.
