时间编码的数字仪表实质是通过中间变换器,将被测量变换成时间间隔,然后再对时间间隔进行数字编码,得出相应的被测值。这种仪表加以适当变换可以测量电压、电流、频率、相位、时间等物理量。根据时间编码数字仪表的作用原理看,它可分为两部分,一部分将被测量变换为相应的两个脉冲,另一部分是对两个电脉冲间的时间间隔进行数字编码。 Time code digital instrumentation is essentially through the intermediate converter, will be measured into a time interval, and then the digital encoding of the time interval, resulting in the corresponding measured value. This instrument can be properly converted to measure the voltage, current, frequency, phase, time and other physical quantities. According to the principle of time code digital instrumentation, it can be divided into two parts, one part will be measured converted to the corresponding two pulses, the other part is the digital interval between two electrical pulses.
