ECET 20700 - AC Electronics Circuit Analysis

Credit Hours: 4.0.

AC circuits including the j operator, phasors, reactance and impedance are studied. Circuit laws, network theorems, and the fundamental concepts of Fourier analysis are applied and used in the study of topics such as passive filters, IC filters, amplifiers, resonant circuits, single-phase and three-phase circuits. Computer aided analysis of circuits is used.

Learning Objectives:

1. Calculate phasor and time domain representations of a sine wave.

2. Analyze series, parallel, and series-parallel passive and active AC circuit.

3. Analyze multi-loop, multi-source AC circuits using mesh analysis.

4. Calculate parameters associated with an amplifier’s frequency response, gain bandwidth and slew rate.

5. Derive frequency response transfer functions for simple passive and active networks.

6. Apply Fourier analysis techniques to calculate the response of passive and active networks to non-sinusoidal signals.

7. Analyze and design given series and parallel resonance circuits.

8. Compute real, reactive, and apparent power, and the power factor.

9. Analyze three phase Y and delta networks.

10. Evaluate the performance of each of the circuits described above, using appropriate standard laboratory measurement procedures, and simulations.
