| Abstract: | The article introduces the principle,hardware design of the high-precision multi-parameter measurement system based on DSP.In one hand,using embedded DSP module structure,through controlling A/D conversion circuit by TMS320F206,we achieve multi-channel high-precision measurement of amplitude.In another hand,we can not only use DSP and PLL circuit to measure high-precision frequency and phase but also use DSP and 89C2501 to measure electrical energy.The design has been applied to multi-channel parameters mea... |
