摘要
Abstract
The design of the anti-jamming DDS system realized by using FPGA is introduced. The design scheme of the DDS system,design of phase accumulator,phase amplitude switching circuit and control circuit are elaborated. The simulation result control schematic diagram of the DDS system realized by using FPGA are offered in this paper. The adaptive IIR notch fil-ter is used as filter module to enhance the anti-jamming effect of the system.关键词
