Annotation
Course explains basic terms and methods for continuous-time and discrete-time signal and system analysis.
Study targets
Students will learn fundamental topics of signal processing for many areas like digital communication, measurements, acoustics, multimedia technology and other signal processing related specializations. the course gives explanation of basic terms used ti describe and analyze signals and systems in continuous and discrete time.
