  • DDFS spurious signals due to amplitude quantization in absence of phase-accumulator truncation

    Publication Year: 2009, Page(s):485 - 492
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1330 KB)

    Spurious signals in direct digital frequency synthesizers (DDFSs) are partly caused by amplitude quantization and phase truncation, which affect their application to many wireless telecommunication systems. These signals are deterministic and periodic in the time domain, so they appear as line spectra in the frequency domain. Two types of spurious signals due to amplitude quantization are exactly ...
