商品簡介
Theoretically superior to older analog systems and ideally matched to semiconductor technology, pulse code modulation (PCM) is the dominant communications technology for many applications including telecommunications, telemetry, data recording, and data acquisition. Veteran professional engineer Waggener elaborates on the art and practice of PCM systems design to conceive of the big picture in designing the systems architecture to fulfill the required application specifications. From sending signals to receiving them, the text focuses on the PCM basics and processes implicated in applied engineering; sampling, quantization, and noise; wireless systems; cable systems; PCM encoding and modulation; demodulation and detection; and synchronization.
