Everyone have theirs choice and comfort in learning through books and prefer one author(s) over another.
For concepts what is your preferred book and why?
- Digital Signal Processing - John G. Proakis & Dimitris K. Manolakis
- Discrete Time Signal Processing - Alan V. Oppenheim & Ronald W. Schafer
I did not learn from DTSP but DSP by Proakis et al is very nice.
