Critical review of "Digital Signal Processing" (PDF) by Ganesh Rao: scope, strengths, and gaps
Unlike purely theoretical books, Rao touches upon the architecture of DSP processors (like TMS320) and real-world applications: speech processing, noise cancellation, and biomedical signal analysis.
To help you decide if this PDF is right for you, here is a quick comparison:
| Feature | Oppenheim & Schafer (Standard) | Proakis (Advanced) | Ganesh Rao (New PDF) | | :--- | :--- | :--- | :--- | | Focus | Deep theory & Math rigor | Algorithmic complexity | Exam success & Syllabus mapping | | Language | Dense, formal English | Technical American English | Simple, student-friendly English | | Filter Design | Extensive theory | Very extensive | Step-by-step procedural approach | | MATLAB Focus | Moderate | High | High (with specific code snippets) | | Best for | Research & Masters | PhD & Core R&D | Undergraduate (BE/B.Tech) & GATE |
Conclusion: If you are an undergraduate engineering student in India preparing for semester exams, the Digital Signal Processing PDF by Ganesh Rao new is arguably better than Oppenheim for your immediate needs.
If you are an engineering student looking for the most popular DSP book used in Indian universities, you might be thinking of "Digital Signal Processing" by P. Ramesh Babu.
