Teacher Area of Knowledge Department

This subject is oriented from a practical and descriptive point of view, eliding the mathematical complexity of a deep study of these matters. The student must learn to analyze signals and linear systems related to the time and frequency domains. In the first units, signals and systems, both continuous and discrete, are studied in deep, including the mathematical models that are applied to represent physical magnitudes and media and the tools used to make those representations. Then, the subject is focused on the linear, time-invariant (LTI) systems and their properties. The methods,both convolutional one with the system\'s impulse response, and frequency one in the trasformed domain (transference function), for analyzing are studied. The unit devoted to sampling is of great importance and makes easier the comprehension of continuous/discrete relations and the discrete representation of continuous cases. The last unit is devoted to Z transform to study discrete systems. The last part of this subject links to the subject of Audiovisual Signal Processing in the fifth term, that will focus specifically on techniques of discrete signal processing. Necessary Previous Knowledge According to the syllabus of the course, the study of System Analysis must go together with Fourier Series and Analysis, that is also placed in the second term and, therefore, it is recommended to study both subjects during the same term. A good mathematical training, that can be achieved in the subject of Calculus, is required. It is also highly useful the subject of Circuit Theory. They both are placed in the previous term
