SHOW ALL WORK STEP BY STEP!!!

Compute the unit-pulse response h[n] for n=0. 1. 2 for the discrete time system y[n + 2] + 1/2y[n + 1] + 1/4y[n] = x[n + 1] - x[n] Determine is each of the following signals is periodic. If a signal is periodic, what is its period? x[n]=3sin(100n) x[n]=4cos(1.5np) For the discrete signals defined as the following: x[0]=4. x[1]=1. x[3]=-1. x[n]=0 for all other integers n. v[0]=1. v[1]=-2, v[2]=3. v[3]=-4. v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n 0.

Explanation / Answer

y[n+2] +y[n+1]/2 +y[n]/4 = x[n+1] -x[n]

1) unit step responce :: x[n] =u[n]

  

    y[n+2] +y[n+1]/2 +y[n]/4 = U[n+1] -U[n]
