WebDec 28, 2024 · As case study for the described parallel DDC algorithm, an ADC sampling clock of 5 GHz with 12 bits vertical resolution and a signal bandwidth of 500 MHz with carrier in the C-Band are considered: this is an actual scenario for the wide band fully digital receiver shown in Figure 1. WebMay 15, 2024 · The "Demodulator Spectrum" is a 64 kHz (or smaller, depending on user DDC bandwidth selection) display around the tuned frequency. With a 64 kHz or larger DDC selection this is 64 kHz wide, but below 64 kHz DDC selection reduces this to match the DDC selection.
Design and Analysis of a Digital Down Converter
WebThe digital down-converter provides 24 selectable output bandwidths ranging from 20 kHz to 4 MHz. The receiver's selectivity can be adjusted with 1 Hz resolution. The … WebAug 13, 2024 · The working principle of DDC is to transform from high sample rate to low sample rate conversion with sufficient gain. DDC can be divided into two main types; wideband DDC and narrowband DDC. Wideband DDCs have bandwidth above 1 MHz which is suitable for 4G WiMAX and satellite applications. rockfish divers
