Course description and aims

 The lecture reviews Fourier transform and inverse Fourier transform, and explains fundamentals of stochastic processes such as modulation signals. In addition, the lecture details bandpass signals and equivalent lowpass representations of the bandpass signal, and explains sampling, quantization, coding and pulse transmission for baseband transmission. Furthermore, amplitude modulation, quadrature amplitude modulation, frequency modulation, and phase modulation are discussed as modulation schemes, and students are required to learn fundamentals of these modulation schemes and theoretical performance of the demodulation.
 The lecture aims to make students completely understand basic theories and techniques of digital communications.

Student learning outcomes
