two arguments are passed through the function input signal and one independent variable. input function is declared by variable ‘sig’. Both the variables passed through exp function. Here input function is exponential function which is represented by exp syntax. Variables var 1 and var 2 are used to create input functions. In this example also two symbolic variables are declared var1 and var2. z transform of an exponential function is also represented in form of z. The input function is declared by the variable ‘sig’. Here input function is an exponential function that is represented by exp syntax. In example 2, two symbolic variables are declared var1 and var2. the output of ztrans function is in the frequency domain, it gives numerator as well as denominator values. We get the mathematical equation in form of z.
Then we applied ztrans function on the input signal. therefore we created one symbolic variable ‘n’ so the input signal becomes cosine of ‘n’. To create a discrete-time function we need one symbolic variable. Input function declared as ‘sig’ variable. In this example we have assumed a simple input signal which is a cosine function. Examples of Matlab Z Transformįollowing are the examples are given below: Example #1 by using the above equations we can convert the discrete domain into the frequency domain similarly we can also convert the frequency domain signal into a discrete-time domain signal by using ‘iztrans’ function. To calculate z transform we can use any type of input equation or signal, vectors, arrays, multi-dimensional matrices are also allowed as input functions. The above equations are used to calculate the z transform of LTI systems, equation 1 is applicable for bilateral systems, and equation two is applicable for unilateral systems.

If z transform is unilateral then it assumes a range between zero to infinity and if z transform is bilateral then the range is between minus infinity to plus infinity. it covers complex differential equations into simple mathematical equations. Z transform helps to perform analysis of linear time invariant systems or signals.
