Fourier series and Fourier transform are applied to signals to set the ground work for the modulation techniques introduced in later chapters. Various baseband signals, including duo-binary baseband signaling, are generated and the spectra are examined to detail the unsuitability of these signals for accessing the public switched network. Pulse code modulation and time-division multiplexing circuits are examined and simulated where sampling and quantization noise topics are discussed. We construct a single-channel PCM system from transmission to receiver i.e. end-to-end, and import real speech signals to examine the problems associated with aliasing, sample and hold. Companding is addressed here and we look at the A and mu law characteristics for achieving better signal to quantization noise ratios. Several types of delta modulators are examined and also the concept of time divisionmultiplexing is considered. Multi-level signaling techniques such as QPSK andQAMare analyzed and s | | 出版日期 | Book 2007 | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-031-79758-3 | | isbn_softcover | 978-3-031-79757-6 | | isbn_ebook | 978-3-031-79758-3Series ISSN 1932-3166 Series E-ISSN 1932-3174 | | issn_series | 1932-3166 | | copyright | Springer Nature Switzerland AG 2007 |
