## Region of Convergence of Z Transform Properties

The z-transform exists when the infinite sum  converges. The sum may not converge for all values of ‘z’. The value of ‘z’…

## Inverse Z-Transform with Examples

represents the discrete time fourier transform of (r^-n*x (n)). The Fourier inverse of X (r*e^ (j*ω)) is x (n)*(r^-n) = (1/(…

## Z-Transform Basics with Formulas

The Z-Transform is the discrete time counter part of Laplace transform. Z-transform allows us to perform transform analysis …

## Hamming Code with Example

For a hamming code, n = (2^m)-1 k = (2^m)-1-m n-k = m,      where m>=3. If this condition is satisfied then the code is c…

## Lempel Ziv Algorithm with Example

Coding for sources with memory:                  A drawback of Huffman’s code is that it requires simple probabilities. For…
