- Linear time invariant systems
- Analog modulation: amplitude modulation, frequency modulation
- Sampling theorem: sampling theorem for low-pass signals, sampling theorem for band-pass signals, sampling kernels
- Digital modulation: frequency shift keying, phase amplitude modulation
- Stochastic signals: spectral properties, correlation, noise
Exercise:
Problems and examples related to Fourier transform, analytical signals, linear time invariant systems, simple AM and FM transceivers, sampling and interpolation filters, digital modulation schemes and stochastic systems.
