The course focuses
on basic analog modulation/demodulation techniques and stability analysis for linear time-invariant analog systems. Specific topics include amplitude modulation using harmonic and periodic impulse carriers, frequency/phase modulation, and associated demodulation techniques. General stability aspects and specific criteria for feedback systems are also introduced. Additional subjects include state-equation description of analog systems and basic introduction to the synthesis of electrical circuits. |
