Final answer:
To determine the response to input x[n]=(2)ⁿ u[−n−1] of the anti-causal system described by given the difference equation: y[n]−(3/4)y[n−1]+(1/8)y[n−2]=x[n]+0.25x[n−1], the difference equation needs to be solved using the given input.
Step-by-step explanation:
To solve for the output of an anti-causal system given the input x[n]=(2)^n u[-n-1] and the difference equation, one would typically employ the Z-transform. ;To determine the response to input x[n]=(2)ⁿ u[−n−1] of the anti-causal system described by given the difference equation: y[n]−(3/4)y[n−1]+(1/8)y[n−2]=x[n]+0.25x[n−1], we need to solve the difference equation using this input.
Step 1: Substitute the given input x[n]=(2)ⁿ u[−n−1] into the difference equation.
Step 2: Simplify and solve for y[n].
The detailed solution involves substitution and algebraic manipulation.
