Design and Implementation of a Re-configurable Versatile Direct Digital Synthesis based Pulse Generator
(2021-07-02)
Direct digital synthesis (DDS) technology has replaced many traditional analogue circuit functions. The frequency, amplitude and phase of a waveform generated using DDS can be precisely controlled. It is possible to achieve ...
Design and Implementation of a Reconfigurable Wideband Radio Frequency Spectrum Analyzer with Image Rejection in the Digital Domain
(2021-02-19)
Most existing radio frequency (RF) spectrum analyzers use conventional superheterodyne architecture to remove images associated with the down conversion of RF input frequency to some intermediate frequency (IF) for further ...
