A discrete-time signal x[n] with the z-transform X(z) = z4+z²-2z+2-3z¯4 is applied to an input to a linear time invariant system with the impulse response h(n)=20(n-3). The output of this system at n = 3 will be.: Select one: O a.4 O b. zero O C.-6 A discrete-time signal x[n] with the z-transform X(z) = z4+z²-2z+2-3z¯4 is applied to an input to a linear time invariant system with the impulse response h(n)=20(n-3).
