What is Reddit's opinion of Signal Processing First?

From 3.5 billion Reddit comments

Disagree. Signal processing is not exactly central to "computer engineering" curricula in most accredited universities.

The book you reference, although a fundamental and essential book in the field, is also one laden thick with theory, and would only serve to discourage a high-school senior. If OP was asking about DSP however, I would recommend another book instead: Signal Processing First

Signal Processing First by McClellan is what we used. DSP never really peaked my interest so I can't say how good or bad of a book it is.

Oppenheim and Schafer is too advanced for an intro. I would recommend Signal Processing First by McClellan, Schafer, and Yoder. It is the book I learned with in college.
