WebA Digital Down Converter is basically complex mixer, shifting the frequency band of interest to baseband. Consider the spectrum of the original continuous analogue signal prior to digitisation, as shown in Figure 2, because it is a real signal it has both positive and negative frequency components. If this signal is sampled by a In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The process can preserve all the information in the frequency band of interest of the original … See more A DDC consists of three subcomponents: a direct digital synthesizer (DDS), a low-pass filter (LPF), and a downsampler (which may be integrated into the low-pass filter). The DDS generates a complex sinusoid at the intermediate … See more DDCs are most commonly implemented in logic in field-programmable gate arrays or application-specific integrated circuits. While software … See more Several variations on the DDC are useful, including many that input a feedback signal into the DDS.

WebNov 1, 2024 · Although unique up-conversion phenomenon has been observed, it is believed that the introduction of Yb 3+ ions will enhance fluorescence intensity in up/down converted luminescence. In this research, Ho, Yb: Y 2 Zr 2 O 7 transparent ceramics were fabricated successfully through vacuum sintering. Web6. I complete Gerard's answer: up-conversion is the reverse process, where two low frequency photons are converted to a single high-frequency photon. So basically down- and up-conversion correspond to a frequency conversion of the photons through a nonlinear interaction. The up/down term correspond to the "direction" of the frequency …
WebThe Digital Down Converter (DDC) is an important component of a digital radio. It performs frequency translation to convert the high input sample rate down to a lower sample rate for efficient processing. In this example the DDC accepts a bandpass signal with a sample rate around 70 megasamples per seconds (MSPS) and performs the following ...
