| Abstract: | A frequency-measurement meter is designed.This system uses CPLD to measure the frequency of the input signal with equal precision.It uses PIC16F877 micro-controller unit as its control part,regulates the system gain from the original 10dB to 40dB gradually(the step is 6dB) with the help of a network composed of digital control trapezium-shaped resistors, and provides digital indications of the system gain and frequency value. |
