Problem 2.1: Rather than doing the details of the convolution, we simply sketch the shapes of 
the waveforms. For a signal s = sc + jss and a filter h = hc + jhs, the convolution 
y = s ∗ h = (sc ∗ hc − ss ∗ hs) + j(sc ∗ hs + ss ∗ hc) 
For h(t) = smf (t) = s(−t), rough sketches of Re(y), Im(y) and |y| are shown in Figure 1. 
Clearly, the maximum occurs at t = 0.
