Course description

Oscillators. Theory of negative resistance oscillators and positive feedback oscillators. High-frequency LC oscillators. Low-frequency RC oscillators. Procedures for enhancement of oscillator amplitude and frequency stability. Oscillators with quartz crystal. Frequency synthesis procedures: direct and indirect synthesis, phase loop synchronisation. High-frequency power amplifiers (class A, B and C). Frequency multipliers. Sine-wave signal modulation: amplitude modulation (AM) and argument modulation (FM and PM), modulator and demodulator structures. Discrete modulation of sine-wave: amplitude shift keying (ASK), phase shift keying (PSK) and frequency shift keying (FSK), modulator and demodulator structures. Pulse modulation: pulse amplitude modulation (PAM), pulse width modulation (PDM), pulse position modulation (PPM) and pulse frequency modulation (PFM), modulator and demodulator structures. Digital modulation procedures: pulse-code modulation (PCM) and delta sigma modulation (DSM), modulator and demodulator structures.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. design oscillators with negative resistance and positive feedback and understand their basic working principles

2. analyse the electrical conditions in LC and RC oscillator circuits

3. understand the structure and working principles of VF power amplifiers

4. design and analyse circuitry for impedance matching

5. understand the basic principles of the modulation procedures based on a sine and pulse signal carrier and evaluate their performances

6. recognise the structure and principle of pulse-coding and delta modulation and implement them
