Downloading the PDF is step one. Here is the "Ganesh Rao Method" to actually learn DSP using this resource:
Step 1: The Cover-to-Cover Scan (Day 1) Open the PDF and spend 1 hour just looking at the chapter titles, the block diagrams, and the problem sets. Do not read the text; map the battlefield.
Step 2: The Formula Highlighter Get a PDF highlighter (or a physical one if printed). Go through and highlight every single formula in red. DSP is formulaic. Create an index of formulas on the first blank page.
Step 3: Solve the "University Questions" Ganesh Rao typically includes a section titled "Previous University Exam Questions." Do not look at the solution first. Try it. If you fail, copy his solution by hand. Handwriting activates motor memory.
Step 4: The Tabular Method Ganesh Rao uses tables for convolution and correlation. Force yourself to use his table method, even if you know the equation method. It is faster and less error-prone.
Step 5: Teach the PDF The final test. Take his block diagrams (like the 8-point DIT FFT) and try to explain them to a friend without looking at the PDF. If you can do that, you have mastered the "better" standard.
