Either the following signals:

 

 f(t)=0 if t<0

 

 f(t)=1−t/2 if 0≤t<2

f(t)=0 if t≥2

And

 g(t)=0 if t<−2

 g(t)=1 if −2≤t≤2

 g(t)=0 if t>2

(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 graphical representation of the signal (h).
