Fourier analysis is a mathematical framework used to decompose signals into their constituent frequency components. The primary distinction between the and the Discrete Fourier Transform (DFT) lies in the nature of the signals they process: continuous-time signals (analog) versus discrete-time signals (digital). 1. Continuous Fourier Transform (CFT)
The CFT is used for continuous, aperiodic signals defined over an infinite time interval. Continuous vs Discrete Fourier Transform | PDF - Scribd
