Signals and Systems (Theriy, 304)

The course aims at educating students on concepts such as signal and system, as well as on a set of mathematical tools and techniques used to analyze and process signals and systems in the time and frequency domains. Upon successful completion of the course, students will acquire the knowledge and skills required in specialized Curriculum subjects such as digital signal processing, analogue and digital telecommunication, networks, hardware design, embedded systems, etc.


Upon successful completion of the course, students will be able to: Knowledge level: 1. Describe the characteristic parameters and properties of the continuous-time signals. 2. Distinguish and recognize elementary time stamps. 3. Identify the different categories of continuous-time systems and describe system connections. 4. Identify the most appropriate way of calculating the output of a linear and temporally invariant system. 5. Choose ways to analyze a continuous-time signal in a sum of single frequency signals. 6. Describe the methodology for calculating the frequency response of a linear and temporally invariant system. Skills level: 1. Calculate the characteristic parameters of continuous-time signals. 2. Calculate the output of linear and time invariant systems through the integral of the convolution. 3. Decompose a signal into a sum of simple sineons through a Fourier Series Expand and calculate the single and double-sided spectrum. 4. Calculate the Fourier Transform of a signal both from its definition and using its properties. 5. Calculate the frequency response of a system using the Fourier Transform. 6. Calculate Laplace's direct and inverse transformation and its convergence region. 7. To solve linear differential equations describing linear and temporally invariant systems, through Laplace transformation. 8. Calculate the transport function of a system using the Laplace transform. At Skills level: 1. Generate the representation of the impulse response when the linear equation of differences described by a linear system is known. 2. Choose the most appropriate way of calculating the spectrum of a signal, depending on its characteristics. 3. Evaluate the differences between the Fourier Series Expand and the Fourier Transform. 4. Explain the physical significance of the Fourier transform and compare spectra of different signals. 5.
