The use of Altera EP2C35 series FPGA chip using the SOPC-NIOSII-EP2C35 board design and simulation of a digital frequency meter, for 1Hz ~ 250KHz pulse frequency measurement using such as precision measurement that the entire internal bands in the measured, can achieve the same accuracy of measurement,with the measurement accuracy independent of frequency,finally,results are displayed on digital
