Design of ultra high frequency digital cymometer
超高频数字频率计的设计

This paper introduces the process of designing UHF digital Cymometer by dividing frequency. This Cymometer has general frequency counter ICM7216D as core component in combination with large scale IC and simple external circuits to measure frequency between 10 kHz to 700 MHz. Simulation results are given as well. Simulation results show that the designed frequency counter works better in 10 kHz to 50 MHz than in 50 to 700 MHz, both of which achieve the requirements.
