dc.description.abstractThis paper deals with the quality requirements of synthesized sine waves reconstructed through a zero- or first- order hold for testing purposes, in particular when a switching demodulator is used. In this case, the interest is to have great spectral purity near the carrier rather than in all of the band. We show that the best method to obtain great spectral purity in the frequency band close to the synthesized frequency is by using zero-order hold instead of a first-order hold. Results show that even though a first-order hold implies a decrease of total harmonic amplitude distortion (THD), the measured spurious harmonics are kept lower or equal when using a zero-order hold in the 15 closest components. We conclude that in testing applications a zero-order hold (in spite of its greater THD) yields better results.
