简易数字频率计:
1、频率计的测频范围为1Hz~10KHz,被测量的信号为TTL逻辑的标准方波信号;2、为提高测量精度,采用计数法(≥1000Hz)和测周法(<1000Hz)相结合的方法进行测量;3、显示器采用6位七段数码管,显示器的无效零应消隐。信号≥1000Hz时不显示小数点,信号<1000Hz时显示小数,小数点后取两位。
-Simple digital frequency meter: 1, frequency of measurement frequency range of 1Hz ~ 10KHz, by measuring the signal for the TTL logic of the standard square-wave signal 2, to improve the measurement accuracy, the use of count (≥ 1000Hz) and test week law ( < 1000Hz) the combination of measurement methods 3, paragraph 6 displays the use of digital pipes, zero should be null and void display blanking. ≥ 1000Hz signal does not show the decimal point, the signal < 1000Hz display decimal, decimal take two.
