Assignment details
This assignment has 2 parts:
- Part 1: Let's check that you're comfortable with convolution and the lock-in amplifier design;
- Part 2: Modify your instrument to include a lock-in amplifier and temperature control.
Turn in all of your work (comprehensive list below) on Stellar in a single PDF file named <lastname><firstname>Assignment8.pdf. |
Turn in:
- answers to all questions in Assignment 7, Part 1;
- a technical subsection of a lab report:
- Apparatus:
- Document your instrument design.
- Describe your apparatus with sufficient detail for another person to replicate your work. Assume the reader is familiar with the concepts of 20.309 and has access to course materials.
- Detail your electronic and optical subsystems. Include component values, gain values, cutoff frequencies, lens focal lengths, and relevant distances.
- It is not necessary to document construction details, unless you built an instrument that was significantly different than the lab manual suggested.
- Refer to schematics and diagrams in the lab manual instead of copying them into your report. Use reference designators (such as R7, C2) to refer to call out particular components in schematic diagrams.
- Why not include a nice snapshot or two of the instrument? So lovely.
- Document your instrument design.
- Apparatus:
