    1. The problem statement, all variables and given/known data

    Can some body differentiate laplace,fourier,Z-transforms?

    2. Relevant equations

    3. The attempt at a solution

    they are related to engineering field. Z-transforms used in discrete signals?

    Yes, Z-Transforms are used for discrete signals. It is the discrete-time equivalent of the Laplace Transform. The discrete-time form of the Fourier Transform is called the Discrete Fourier Transform, or DFT.

    As for your original question, you'll have to phrase it much better.
