Signals and Linear Systems (EEE-3111): Special Suggestion for Midterm, Summer 2014

This suggestion does not guarantee A+, it just covers the most important questions.

Theory:

• Definitions: Signal, Systems, Classification of various signals, Basic system properties (Linearity, Causality etc.), Basic properties of LTI systems (Associative property, Distributive property etc.), PSD, Autocorrelation.
• Unit Step function and Unit Impulse function.
• Shifting property of unit impulse function.

Math:

• Shifting, Compressing a given signal (discussed in class in detail).
• Draw signals from given equations.
• Linearity, Time-invariance, Causality check of systems (examples and also exercises given in the last class).
• Power and Energy calculation of signals.
• Examples reviewed in class are VVI.

Thank you and good luck.

Electrical Circuits II (EEE-1213): Syllabus Overview for Midterm, Summer 2014

Theory:

• Branches: R, L, C, RL (2 will come in the exam)
• Definitions: AC, Phasor, Period, Frequency, Angular Frequency, Phase, Phase Difference, Form Factor, Peak Factor etc.
• Calculation of Average & Effective value of a sinusoidal wave (discussed in last lecture)

Math:

• Phasor Algebra (at least 6 marks)
• Leading / Lagging (at least 5 marks)
• Impedance (Z) Calculation
• Determination of Period, Phase angle, Angular frequency etc. from a given wave

Thanks everyone. Good luck!
