Either the following signals:

f (t) = 0 if t <0 g (t) = 0 if t <−1

f (t) = 1 - t if 0 ≤ t <1 and g (t) = 1 if - 1 ≤ t ≤ 1

f (t) = 0 if t ≥ 1 g (t) = 0 if t> 1

(i) Give the graphical representations of the signals (f) and (g).

(ii) Give a physical meaning of the convolution product of two signals.

We set h (x) = f (t) *g (t) where '*' represents the convolution product.

(iii) Determine the signal (h).

(iv) Give the graphic representation of signal (h).
