Course objectives
The course is focused on digital processing of one-dimensional signals in physics, monitoring technology and other areas.
Learning outcomes
Upon completion of the course, the student will be able to: Describe and explain the term Continuous, discrete, digital signal, application areas, stages of signal processing, classification of discrete signal processing methods, advantages and disadvantages of discrete and digital signal processing, 1D, 2D signals, multidimensional.
describe and explain the Fourier series (FS) and the Fourier transform (FT) of a continuous signal. Definition and characteristics, FT of basic signals, describe and explain the Transmission function, impulse response of the system, distortion (binding to the transmission bandwidth).
describe and explain Digital filtration and construction of digital filters – FIR, IIR (numerical realization of convolutional integral, low-frequency filters for noise removal, narrowband filters, nonlinear filters, filters for removing shots).
