This page is the review sheet for Test 2 for [[EGR 224]] for Summer, 2020.  It is still in draft form as of 6/12/2020.

== Coverage ==
While the test is, by nature, cumulative, there will be certain aspects of the Electrical Fundamentals of Mechatronics which form the core of this test.  Specifically, topics from lectures 9-18, HW 5-8, and the accompanying labs.  More specifically, topics include, but are not limited to, 
# Reactive elements (capacitors and inductors)
## Know the basic voltage/current relationships
## Know the continuity conditions
# DC steady-state analysis of reactive circuits
## Capacitors act like open circuits
## Inductors act like short circuits
# AC steady-state analysis of reactive circuits
## Phasor analysis for single-frequency sources
## Phasor analysis coupled with superposition for circuits with sources at different frequencies - you can either do each individual component of all the sources independently or group components by frequency.
# Impedance and transfer functions
# Filters
## Be able to determine filter type by transfer function
## 1st order filters
### Determine cutoff frequency (half-power or -3dB frequency) and filter type
### Be able to determine filter type given a circuit '''or''' design a circuit given a filter type.  This type of question would be limited to voltage-to-voltage filters
## 2nd order filters
### Be able to determine filter type given a circuit
### For high-pass or low-pass filters, be able to determine cutoff (half-power) frequencies (no tricky cases)
### For band-pass filters, be able to determine bandwidth, quality, damping ratio, cutoff frequencies, logarithmic center frequency, and linear center frequency
### For band-reject filters,  be able to determine quality, damping ratio, cut-on frequencies, logarithmic center frequency, and linear center frequency
### Be able to design a band-pass or band-reject filter given sufficient information (some combination of bandwidth, quality, damping ratio, cutoff/cuton frequencies, logarithmic center frequency, and linear center frequency.  
# Bode plots
## Be able to sketch Bode magnitude and phase plot approximation for multiple zero/pole system '''assuming''' poles and zeros are at least a decade away from each other (i.e. no tricky cases)
## Be able to interpret Bode magnitude plot with respect to bandwidth, quality, damping ratio, cutoff/cut-on frequencies, logarithmic center frequency, and linear center frequency
# Frequency and Time Domain Relations 
## Determine transfer functions between a source and an output
## Determine differential equation using time or frequency techniques
<!--
# Laplace Transforms
## Understand the concepts of impulse response and step response for LTI systems and their relationship to the transfer function
## Be able to set up and solve circuit equations using Bilateral Laplace Transform versions of impedance equations
## Be able to set up and solve circuit equations using Unilateral Laplace Transform equivalents of inductors and capacitors with initial conditions other than 0.
##*Specifically, know how to replace a capacitor or inductor with a version storing no initial energy in series with an appropriate voltage source or in parallel with an appropriate current source.
## Be able to solve differential equations with given initiation conditions.
## Know the MOAT forwards and backwards and be able to use it to solve problems using Laplace transforms.
## Be able to use partial fraction expansion to help with inverse Laplace transforms of relatively simple frequency space representations. Note: no repeated roots will be given.
-->
<!--
# Operational Amplifiers
## Know the requirements for the Ideal Op-Amp Assumptions (feedback between the output and the inverting input), the Ideal Op-Amp assumptions (infinite internal input impedance, zero internal output impedance, and infinite internal voltage gain), and the results of the Ideal Op-Amp Assumptions given feedback to the negative input (no voltage drop across the input terminals and no current into/out of the input terminals).
## Know how to analyze and build buffers, noninverting and inverting amplifiers, summing and difference amplifiers.
## Know how to analyze non-standard configurations (i.e. every other kind of circuit with an OpAmp, including those with reactive elements).
