i asked for help bcoz i have no idea how to solve itYou first.
Have you learned about z-transforms yet? This problem is straightforward in the frequency domain. If you have been taught z-transforms, we can guide you through the process which begins by taking the z-transform of your difference equation and then solving for H(z)=Y(z)/X(z). Then you take the inverse z-transform (using partial fraction expansion and a transform table) to work back to the impulse response funtion h[n].i used the conv function with values of h and x to find the convolution
but i dont know how to de the reverse
