Fourier analyses of periodic and aperiodic signals, signal spectrum. Signal power and correlation between random signals.
Signal filtering and convolution. Sampling and reconstruction of bandlimited signals. Pulse transmission and intersymbol interference, Nyquist theorem.
Basics of information theory: events and information measure. Information sources, entropy and source coding. Communication channel model and channel capacity.
The subject is taught in programs
