The hints page (now reposted to fix a missing '+' sign) for Set 7 has two added pages to help out with Problem 6.

Lecture video 10a posted. The filter design and multirate document is corrected in the interpolator lowpass example.

Set #8 and Set #8 with hints now posted. This set starts coverage of Chapter 4.

I posted a fix in the Project 1 Jupyter Notebook sample, to remove rate_change() object and replace it with mrh.multirate_IIR(). This applies to interpolator and the decimator design.

A summary of filter design, interpolation, and decimation for Project 1 is now posted as a PDF under the project tab. The older version of this document was in notebook form, but I think the PDF is better since you can cut and paste from it.

I have reposted a new Configuring Anaconda and Virtual Environments blog page linked in the lower right column to now show how to set up interactive matplotlib plots. Very nice so far.

The markdown editor Typora provides an easy way to export Jupyter notebooks to .md then open in Typora and export directly to PDF. You will still need to have Pandoc installed, but no LaTeX needed.
