摘要

介绍了一种能够在20hz ~ 20khz频率范围内快速比较电感与交流标准电阻的数字采样系统。它还可以精确测量大电流或高电压下的电感。在低音频范围内，从10mH到10H的电感器可以以最小的相对不确定度在106中测量50到100个零件。

A fast L-R comparison system by digital sampling measurement approach

A digital sampling system which can fast compare inductors with ac standard resistors in the frequency range between 20 Hz and 20 kHz is described. It can also precisely measure inductance at heavy current or high voltage. Inductors from 10mH to 10H in the low audio frequency range can be measured with the least relative uncertainty of 50 to 100 parts in 106.
