摘要：
A new frequency measurement system, which is suitable for a wide range of microprocessor-based applications is presented. The procedure used to calculate the frequency is based on the original double buffered method. This new method utilizes both pulse counting and measurement of the fractional pulse period during the fixed sampling time. The sampling time can be chosen to provide high accuracy and high resolution over a wide range of frequencies. Therefore, it is specially applicable in digital tachometers.
