Since you asked for an "interesting paper" within the context of this book, Taub and Schilling are famous for their treatment of Quantization Noise in PCM (Pulse Code Modulation).
The Concept: In early communication theory, it was difficult to calculate the Signal-to-Quantization Noise Ratio (SQNR) for non-uniform signals (like voice). Taub and Schilling provided a simplified model treating quantization error as additive noise uniformly distributed between $\pm \Delta/2$. E_b = E_s (for 1 bit/symbol).
This leads to the famous derivation found in their text: $$ S/N \approx 4.8 + 6n \text dB $$ Where $n$ is the number of bits per sample. This equation (and its derivation in their Chapter on PCM) is fundamental to the design of digital telephony and audio CDs. It explains that for every bit added to the sample, the signal-to-noise ratio improves by 6 dB.
