( 2 ) the digital main experiment board is designed , in this scheme , the analog multiplexers are taken as the nodes selectors to construct the 16 nodes structure of the experiment board . the connection of the nodes of devices can be digitally set . the dcp ( digital control potentiometer ) is selected as the resistor library component , the capacitances and the inductances with the different parameters respective are selected as the capacitance library components and the inductance library components , the parameters of components are set with the analog multiplexers
( 2 )研制了全数字化实验主板，本方案选择模拟电子开关组成16选1的节点选择器，构成了16节点的通用实验主板，可数字化设置实验主板上的元件节点的连接，选取数字式电阻作为实验电阻的元件库，选取不同参数值的电容和电感组成电感元件库和电容元件库，由模拟电子开关对电容和电感元件参数作数字化选择。
