Course description:
ENSC 320 is a second course on electric circuits. It is intended both
to enhance the knowledge of students with regard to electric circuits and
to develop skills in analysis. Although the focus is electric circuits,
the theory and skills learned are useful in other areas as well.
For example, the ability to analyze electric circuits gives one the
ability to analyze systems incorporating many other phenomena,
such as mechanical, thermal and acoustic, where other physical quantities
play similar roles to those of current and voltage.
Prerequisites: ENSC 220.
TOPICS:
- Analysis of Circuits in the Time Domain:
Review of differential equation analysis of linear circuits. Treatment of initial conditions. Zero state and zero input responses. Properties of more general linear time invariant systems in continuous time. Convolution, unit impulse.
- Laplace Transform Analysis of Circuits:
The Laplace transform and its inversion by partial fractions. Properties: multiplication-convolution, differentiation, initial and final value theorems. Circuits in the s-domain: transfer function, impedance, circuit reduction, initial conditions. Series and parallel decompositions. Pole-zero diagrams related to time domain behavior.
- Frequency Response, Filters, and Resonance:
Frequency response. High-pass and low-pass networks. Half-power frequencies. Frequency response from pole-zero locations and Bode plots. Bandpass filters and resonance. Natural frequency and damping ratio. RLC series circuit; series resonance. Quality factor. RLC parallel circuit; parallel resonance. Practical LC parallel circuit. Series-parallel conversions. Locus diagrams.
- Filter Design:
Filter classes: Butterworth, Chebyshev. Implementation diagrams, quadratic sections. State variable description. Active filter implementation: Sallen-Key and state variable filters. Other active filter configurations.
- Mutual Inductance and Transformers:
Mutual inductance. Coupling coefficient. Analysis of coupled coils. Dot rule. Energy in a pair of coupled coils. Conductively coupled equivalent circuits. Linear transformer. Ideal transformer. Autotransformer. Reflected impedance.
- Two-Port Networks:
Terminals and ports, z-parameters. t-equivalent of reciprocal networks. y-parameters. Pi- equivalent of reciprocal networks. Applications of terminal characteristics. Conversion between z and y parameters. h and g parameters. Transmission parameters. Interconnecting two-port networks. Choice of parameter type.
