Description: This system is a CPLD microcontroller for signal frequency and period, time interval and the duty ratio of digital frequency measurement meter based on the system by the AGC (automatic gain control) circuit, amplifier circuit, high speed broadband comparison circuit to achieve effective value of 10mV/ 100MHz and the frequency of processing components, including AGC circuit control signal after amplification is consistent within a certain range of amplitude automatic gain circuit compares the former circuit output signal is converted into CPLD, using precision frequency measurement principle, realizes high accuracy time gate 1S. SCM communication processing data and display, data show that the system precision to play a part of the requirements.
