If you share which specific topic (e.g., FM noise performance, PCM quantization, QPSK BER) you need help with, I can explain the principle as the book would—equations, diagrams, and all—without infringing copyright.
The "extra quality" you are looking for lies in the book's ability to derive complex results (like the error probability of a digital receiver) using fundamental calculus and probability, rather than skipping steps. It remains a gold standard for rigorous communication theory. If you share which specific topic (e
In communication theory, the difference between φ (phase), ω (frequency), and ψ (waveform) is everything. Low-resolution scans often merge these characters into unrecognizable blobs. Worse, subscripts like n(t) (noise) versus s(t) (signal) become indistinguishable. In communication theory, the difference between φ (phase),
