Abstract
In order to effectively improve the system performance of the filter with non-adjustable frequency,and reduce the resource consumption of the filter based on FPGA,an efficient filter with adjustable frequency based on FPGA is proposed. The hardware platform is designed for the filter with adjustable frequency,which is composed of the MCU module,FPGA wave-form module,amplitude module,digital model conversion module,low-pass filter conversion module,keyboard input module and LCD module. The MCU controls the adjustable frequency for the core module. On the basis of the waveform signal generated by DDS technology ,the signal strength of the filter is determined. The distributed algorithm is used to realize the software de-sign of the filter. The experimental results show that the proposed method can improve the accuracy of the filter with adjustable frequency effectively.关键词
