Sinopse:
Digital signals are not confined to specialized hardware — they flow through every smartphone, every audio stream, and every sensor network that modern software touches. This textbook opens with signals in the physical world, translating sensation into multimedia, then builds a rigorous bridge from continuous phenomena to discrete digital representations through chapters on sampling, quantization, and the frequency domain. The early treatment of feedforward filters as delay operators sets a hands-on pattern that runs through the entire book. The middle chapters tackle the full signal processing pipeline: Fourier analysis, FIR and IIR filter design, the z-transform, and spectral analysis — all presented with computational implementations rather than passive mathematics. Later sections extend into real-world applications including audio processing, image filtering, and communication signals, with each chapter offering exercises and further reading that connect theory to engineering practice. At over 200 pages with dual authorship from University of Washington faculty, this is a complete undergraduate introduction that treats signals as a software discipline rather than a hardware afterthought. Students in computer science, electrical engineering, and applied mathematics will find a text that respects computation as the primary lens — not a side note — for understanding how signals carry information and how systems extract meaning from noise.
