| Abstract: | In engineering and laboratory research, the dynamic periodic and aperiodic complicated waveform signals are often required. Digital look-up table method for synthesizing periodic signals is the most popular technique for direct digital frequency synthesis. The method is capable of very high frequency resolution if the technique of fractional addressing is used for. the text point to the special configuration of FM signal ,analying the algorithm realization of FM signal by FPGA(Field Programmable Gate Array),choosing the correlate parameters. decising the err.the request of the specify targets is arrived after simulink by matlab. The shape of wave is all right after accomplished using hardware. |
