the following are impulse responses/outputs ofdiscrete -time LTI systems. Determine whether each system is causaland/or stable. justify your answers
1. h [n] = 1/5^n u [n]
2. h [n] = 5^n u [3-n]
3. y [n] = 3x [n] - 0.15y [n-1]
4. y [n] = 2e^-x [n]
5. y [n] = n^2 4x [n]
B. Show if the systems defined in 1 to 5 above havebounded input and output (BIBO) from the summation of their impulseresponses for n = 0, 1,2,3,4.
