Prerequisite for enrollment of the subject: Passed: Mathematics 2

Course Goals (acquired competencies): Knowledge of the fundamental methods for transmitting telecommunications signals between transmitter and receiver, such as modulation, demodulation, sampling, quantization, encoding, and detection of binary signals. Knowledge of the basic limiting factors for transmitting signal through a telecommunications system, such as intersymbol interference and thermal noise. Determining the shape of the signal and the signal-to-noise ratio at the receiver.
