Features: Chapters 1 to 6 of this book primarily cover the basic principles and concepts related to analog signal digitization and corresponding data word signal transmission in digital communication technology. The main content includes: the fundamental principles of PCM (Pulse Code Modulation) achieved through processes such as sampling, quantization, and encoding, as well as the concepts of DPCM (Differential Pulse Code Modulation) and ADPCM (Adaptive Differential Pulse Code Modulation) for further compression of encoding rates. To adapt to the development and needs of multimedia technology, modern mobile communication technology, and IP network telephony, the course also introduces the digitization of image signals and low-bit-rate speech coding techniques, such as subband coding and linear predictive coding (LPC). In terms of digital signal transmission, it discusses baseband transmission codes, multiplexing, regenerative repeater transmission, and the principles of digital signal technologies related to the Plesiochronous Digital Hierarchical (PDH) system.
