You can bring any calculator that cannot go online or wirelessly communicate with another device. Graphing calculators are fine.

September / October / November / December / Top / Bottom

These notes are not required reading. They are provided as a courtesy for the interested/curious student.

You lab notes should include:

- a description of what each subcircuit does and how it works
- a discussion of the implementation and testing of each subcircuit in the lab
- plots of the various signals observed on the oscilloscope for each subcircuit
- plots can be neatly hand-drawn with accurate scales and labeled axes
- alternatively, you can take high-quality photos of the oscilloscope display that shows the scales and neatly include print outs in your lab notebook
- a discussion of how all of the subcircuits are connected together in order to acheive the desired analog-to-digital conversion
- a discussion of how the circuit is calibrated so that the digital output matches the value of the analog input
- an overall "timing diagram" showing how the various signals interact to produce the analog-to-digital conversion

We will discuss the various subcircuits in class (we've already covered the Reset Pulse Generator, Clock Generator, and Flip Flop). We will also discuss the operation of the overall circuit and produce the timing diagram.

Here are some practice problems on digital electronics. We won't collect or grade this assignment, however, you should try the problems in preparation for the final exam. Here is a copy of my solutions. I obviously recommend that you try the problems before jumping to the solutions.

Thursday, Dec. 12
19:00 - 21:30
EME 1202

Try the past final exams at the bottom of the page for practice. Note that we did not cover Thevenin equivalent circuits. Therefore, you're not expected to be able to solve the following problems:
2012 - #6
2013 - #3(c)
2014 - #1(a)

The whole video is worth a watch, but first 10 mintues is relevant to what we're doing in class now.

September / October / November / December / Top / Bottom

Start with problems 3,4, & 5. We will start covering the error analysis material needed from problems 1 & 2 this week.

These notes are provided as supplemental material for the interested student. It is not required reading.

I will not collect and grade this assignment, it is for your own practice. The answers are given after each problem. If you struggle with any of the problems, you are strongly encouraged to review the relevant concepts in your first-year textbook or in Santavicca's book.

Python is being support because:
    - It is a commonly-used programming language in physics research and industry
    - It is freely available for anyone to use without requiring a paid-for license

You can write and execute Python code using UBC's Open Jupyter Hub. You don't need to install any software, just log in using your CWL.

As an alternative, you can also write and execute Python code using UBC's Jupyter Hub called Syzygy. You don't need to install any software, just log in using your CWL.

If you'd prefer to write and run code on your own system, you can download and install the individual editions of the Anaconda Toolkit.

You can also refer to this set of Python tutorials that demonstrate how to complete some of the common data analysis tasks that you might encounter.

If you prefer, you can complete your data analysis tasks in MATLAB. UBC students are eligible for a free MATLAB license.

Here is a set of MATLAB tutorials. Although you are free to use MATLAB to complete you lab data analysis, MATLAB support from your PHYS 231 instructor/TA will will be very limited/nonexistent.

If you prefer and, if you have access to it, you can complete your data analysis tasks in Maple. Note that UBC does not have a student license for Maple. Here is a set of Maple tutorials. Although you are free to use Maple to complete you lab data analysis, Maple support from your PHYS 231 instructor/TA will will be very limited/nonexistent.

Note that, to the best of my knowledge, Excel does not easily do weighted fits to data sets. Therefore, in PHYS 231, Excel is generally not a suitable tool for data analysis.

This document also comes from the Phys 121 lab manual used at Case Western Reserve University.
