What is the z-transform of the signal x(n)=[3(2n)-4(3n)]u(n)?
A. 3/(1-2z-1)-4/(1-3z-1)
B. 3/(1+2z-1)-4/(1+3z-1)
C. 3/(1-2z)-4/(1-3z)
D. None of the mentioned
Answer:A
What is the z-transform of the signal x(n)=[3(2n)-4(3n)]u(n)?
A. 3/(1-2z-1)-4/(1-3z-1) B. 3/(1+2z-1)-4/(1+3z-1) C. 3/(1-2z)-4/(1-3z) D. None of the mentioned
Explanation: Let us divide the given x(n) into x1(n)= 3(2n)u(n) and x2(n)= 4(3n)u(n)
