Rachit Saini on Instagram: "No Problem, Here's the information about how to calculate the Z - Transform of a discrete time signal. The Z-transform is a way of converting a discrete time signal, which is just a sequence of values, into another form that is easier to analyze. Instead of working directly with the sequence, we represent it as a function of a new variable called z. Why do we use it? It helps in solving difference equations more easily. It allows us to check stability of systems. It s
