Lecture video 10 is now posted. The chapter 8 notes are reposted with the correct password.

Notes Chapter 8, parts a, b, c, and d posted with sp2020 password. Set #4, the last homework assignment posted. After this we have only the DPLL lab, and the final exam/project outstanding.

I re-posted the DPLL lab sample notebook ZIP and the corresponding PDF. Likely some more issues remain that I cannot see at the moment. The main theme of errors is when I revamped the lab I changed the sampling rate from 44.1 --> 48 ksps and the center frequency moved from 15 --> 16 kHz. I spent over an hour today having PDF export issues with Typora. Very frustrating! With this lab I am guiding you step-by-step from start to finish. Note: moving forward with real-time DSP, errors in pyaudio_helper callbacks do not show runtime errors of any kind. Rather you usually stop getting audio output.

I have posted the updated DPLL lab experiment. The corresponding Jupyter notebook sample has remains to be updated. For those interested in starting read about the lab, you can. I want to stress that solo teams are now mandatory and each student needs to have an Analog Discovery 2 (AD2) and a Sabarent or similar USB audio dongle. A former student has offered to loan his AD2 to one of you in need. He will mail it if need be. If you have a function generator with FM modulation capability and a scope you can get by without the AD 2. You still need the USB dongle unless your PC has a line-in jack.

Set #2 and Set #3 solutions finally posted. It took some time to put Problem 1 of Set #3 together. I hope to get back to the DPLL lab updates sometime during spring break. Everyone needs to have an Analog Discovery (AD) and a Sabarent USB audio device. The AD is on a special Covid-19 sale ($161 vs $179).

Lecture video 9 posted. We have finished Chapter 4 and 5 of the lecture notes and had a good discussion on the midterm. See the questions posted by Ben on Slack.

I just reposted the midterm document to fix an incorrect reference to Set #3.

Learning Python

Python Basics a tutorial written in Jupyter Notebook. ZIP.

Link to Anaconda. This is the scientific Python I recommend.

Two IDE's I recommend are (1) VS Code with the Python extension and (2) Pycharm Community Edition.

NumPy2MATLAB and IPython reference card

Jupyter Lab is ready. Also see, Getting started with JupyterLab (Scipy2018).

Obtaining Mathematica

Mathematica is available across the campus due to the CU system wide site license. This system-site license also means that students may install their own copy on home computers as well. Some links of interest regarding the CU site license for Mathematica are: download and installation and support information.
