quadruple-frequency system
解釋
四頻制-
This system is realized by cpld which can get rid of the disadvantages in one - time design including property liable to jamming, long sampling period, and poor working stability. its sampling period is up to 500ns at least and output delay is only 19. 5ns. a stable period of pulse coming out of quadruple - frequency differential circle belongs to it
完成了用vhdl硬體描述語言對全數字轉速位置測量子系統的設計,並用max ? plusii軟體進行了編譯和波形模擬,在cpld ( max7000 )得到實現,該系統克服以往設計中存在的易受干擾、工作穩定性差、采樣周期太長等的缺點,輸出延時僅為19 . 5ns ,采樣最低周期可達到500ns ,且四倍頻微分電路獲得的脈沖周期穩定。
