The basic function of each type of converter is to convert the information into a form that is convenient for transmission and processing. It requires that the information does not be distorted, distorted, delayed, etc. during the conversion process, so there is a certain degree of linearity, input and output impedance matching and isolation of the converter. Claim:
1 linear characteristics. It is required that the output signal Y of the converter has a good proportional relationship with the input signal X, that is, Y=KX+A, where K and A are constant.
2 input impedance and output impedance. The converter input impedance and output impedance must match the input meter and output meter to achieve high conversion accuracy.
3 isolation characteristics. The input circuit, output circuit and power supply circuit should be isolated from each other at the DC potential, and the grounding points of the input and output circuits F should be separated to improve the anti-interference ability.
