# | WHICH | WHEN | WHAT | WHY |

1. | Fourier series | 1st week |
Using sinusoids to represent a signal |
If can handle sinusoids, can handle anything |

2. | Transfer functions | 1st week |
Effect on sinusoids of linear system |
To describe effect of circuits, filters, systems |

3. | Circuit analysis I | 2nd-3rd weeks |
KVL, KCL, Ohm's law, basic sources |
Basics of EE, as free body diagrams to ME |

4. | Circuit analysis II | 3rd-4th weeks |
Node and mesh, Thevenin/Norton |
Simplify circuit analysis and to model sources |

5. | Op-amps | 5th week |
"Golden rules" for the ideal op-amp |
Op-amps useful for real world |

6. | Inductors & Capacitors | 6th week |
Effects of these two devices on sinusoids |
Need them to design filters |

7. | Complex numbers | 7th week |
Magnitude, phase, polar & rectangular |
Phase relations between input output sinusoids |

8. | Phasors | 8th week |
Complex numbers to represent sinusoid |
Much easier to use sinusoids |

9. | Impedance, admittance | 9th week |
Complex number rep. of R,L,C |
#9,8: use #6,5 and apply #4,3 to analyze #2 |

10. | Filtering | 11th week |
Apply transfer functions to a desired task |
Reduce noise, preemphasis, equalization |

11. | Complex power | 12th week |
Usual and reactive |
Analyze power dissipation in AC |

12. | Bode plots | whole course |
Plot gain and phase of transfer function |
Log-log plots are easy to interpret |
