What is the Z transform of x n?

Explanation: The z-transform of a real discrete time sequence x(n) is defined as a power of 'z' which is equal to X(z)=\sum_n=-\infty^\infty x(n)z^-n, where 'z' is a complex variable.

Concept of Z-Transform and Inverse Z-Transform

The above equation represents the relation between Fourier transform and Z-transform. X(Z)|z=ejω=F. T[x(n)].

What is the Z transform of the signal x n )=[ 3 2 N )- 4 3 n )] u n )?

What is the z-transform of the signal x(n)=[3(2ⁿ)-4(3ⁿ)]u(n)? => X(z)=\frac31-2z^-1-\frac41-3z^-1.

What is the Z transform of the signal x n u n?

Calculation: Given signal, x(n) = an u(n) The z-transform of the above-given signal is given by. X ( z ) = ∑ n = − ∞ ∞ ⁡ X ( z ) = ∑ n = 0 ∞ ⁡
