14. If a Backward Difference System is cascaded with another Backward Difference System, the overall impulse response of the cascade is: a) h[n]=u[n-1] b) h[n]= \delta[n]-2\delta[n-2]+\delta[n-2] c) h[n]= 2\delta[n]-2\delta[n-2] d) none above

Step 1
In a Backward Difference System, the output at time n is given by the difference between the input at time n and the input at time n-1. Now, let's consider cascading two Backward Difference Systems. This means that the output of the first system becomes the input Show more…

A system is formed by cascading two systems as shown in Fig. $15.86 .$ Given that the impulse response of the systems are \[ h_{1}(t)=3 e^{-t} u(t), \quad h_{2}(t)=e^{-4 t} u(t) \] (a) Obtain the impulse response of the overall system. (b) Check if the overall system is stable.
