Pulse frequency measurement design using microcontroller

technology

Abstract:This paper describes the 8051 to measure the pulse period and frequency, the hardware interface circuit and the corresponding software applications.With the development and progress of science and technology, more and more people had a keen interest in radio .The microcontroller for the development of radio technology have an immeasurable effect. This article first introduces the hardware structure of the frequency measurement system, and then explain the classification of pulse frequency measurement method, select the pulse counting method as the method of measurement. The article also draw a flow chart of the system, we can easily understand the whole process, then the frequency measurement method error analysis, and finally by the way of the table describes the relationship between the pulse and frequency.
