Image acquisition design of the AOTF imaging spectrometer based on SOPC

A high resolution DDFS design on VHDL using bipartite table method

“…These are Direct Analog, Direct Digital and Indirect Frequency Synthesizers. Direct Digital Synthesis is the one which provides fast switching speed, very high frequency resolution, low phase noise, ease to control output frequency precisely and utilized in several areas such as communication [1]- [3] test and measurement systems [4], [5], image processing [6] and medical applications [7]. A typical Direct Digital Frequency Synthesizer (DDFS) uses ROMs as Look Up Tables (LUTs) to convert the phase values to amplitude values.…”
