Data Acquisition, Analysis and Processing
FEKT-MZPDAcad. year: 2019/2020
The course is dedicated to the analysis of digital signals in time and frequency domain. Emphasis is placed on the orthogonal transformation in particular on DFT, fast algorithms FFT, and wavelet transformation. Part of the course is devoted to mathematical operations with time series and digital filtering.
