The impulse response of a causal, timevariant system is given by h[n, m] = ma n u[n − m], where h[n, m] defines the system response to an unit impulse δ[n − m]. (a) Find the system response to the...

h[n, m] = maⁿu[n − m], where h[n, m] defines the system response to an unit impulse δ[n − m].

(a) Find the system response to the input x[n] = u[n] − u[n − 11].

(b) Find the system response to the input x[n] = u[n].
