For each of the following difference equations
y[n + 1] + l.5y[n] = x[n]
y[n + 1] + 0.8y[n] = x[n]
y[n + 1] - 0.8y[n] = x[n]
use the method of recursion to solve the following problems:
compute y[n] for n = 0,1.2, when x[n] = 0 for all n andy[-l] = 2.
Compute y[n] for n = 0,1.2, when x[n] = u[n]and y[-l] = 0.
Compute y[n] for n = 0,1.2, when x[n] = u[n]and y[-l] = 2.
