The relationship with Fourier Transform refers to the connection between discrete-time signals and their frequency domain representations. This concept is crucial for analyzing signals in various fields, as it allows us to understand how a signal can be expressed as a sum of sinusoids, revealing its frequency components. In the context of discrete-time systems, this relationship facilitates the use of the Z-transform, which generalizes the Fourier Transform for sequences and provides insight into system stability and frequency response.
