How do you solve inverse Z-transform?

Long Division Method

X(z)=x(0)+x(1)Z−1+x(2)Z−2+......... The above sequence represents the series of inverse Z-transform of the given signal forn≥0 and the above system is causal. However for n<0 the series can be written as; x(z)=x(−1)Z1+x(−2)Z2+x(−3)Z3+.........

What are the limitations of Z-transform?

Limitations – The primary limitation of the Z-transform is that using Z-transform, the frequency domain response cannot be obtained and cannot be plotted.

How do you calculate Z-transform?

Concept of Z-Transform and Inverse Z-Transform

X(Z)|z=ejω=F. T[x(n)].
