A digital fi‘equeney meter designed with FPGA development software Q-~uS 11 is introduced．The 1 Hz—l MHz input measured pulse signals of the digital ii‘equency meter can be uSed for measuring frequency，period，pulse width and duty ratio，etc．The test results stably display O71 3 seven—segment numeric tubes，and the measuring ranges may be switched over automatically．The measuring error is equal to or less than 0．1％．

First of all we would like to thank God Almighty for giving uS the strength and confidence in pursing the ambitions. We would like to thank our Examiner Professor Axel Jantsch for allowing uS to do this under his guidance and encouragement. At the same time we would like to mention our sincere thanks to Mr. Said Zainali, Manager of FRAME ACCESS AB for giving all the required equipment and the technical support which helped uS to finish this thesis. We would like to mention our gratitude to our fellow VACS team members who helped uS a lot during difficult times.
