This course provides learning experiences for students to be able to process a signal and process digital signals with applications in the fields of information, communication and control, explaining the introduction of digital signals, exploring discrete time invariant linear systems, determining Z-transformations, designing analog signal filtering, digital signal filtering: Infinite Impulse Response (IIR), digital signal filtering: Finite Impulse Response (FIR), describes the concept of Fourier transform for discrete signals, fast Fourier transform for discrete signals. Perform Matlab programming for signal processing and digital signal processing. The lecture is carried out in the form of a case method.
