Application Of Direct Digital Frequency Synthesizer In Digital Modulator
碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 92 === Abstract In this thesis, we propose a digital modulator with FSK, DFSK, BPSK and QPSK function by using direct digital frequency synthesizer (DDFS). For DDFS, the spur item were caused by finite output word length, phase truncation and sine/cosine mapping...
