| Abstract: | Firstly,the measurement theory about electric parameters in non-sine circuit is described,and then we discussed the design of instrument.In hardware,the DSP TMS320LF2407A and analog to digital converter ADS8364 is used as the core,some interface circuits are also used to realize the other functions.In software,we adopt the Goertzel arithmetic to realize FFT,cooperates with other software models such as electric parameter arithmetic model and keyboard program model in realizing all of the design functions. |
