## What is the difference between z transform and Fourier transform?

Fourier transforms are for converting/representing a time-varying function in the frequency domain. Z-transforms are very similar to laplace but are discrete time-interval conversions, closer for digital implementations. They all appear the same because the methods used to convert are very similar.

## What is inverse Z transform of constant?

Z transform of any constant is considered **non-exsisting**. But a certain can be taken, like can be taken as function and by replacing with 1 the function becomes constant. For such a function there is formula as And one can solve this by definition of z transform. For the solution z lies between to.
