| Abstract: | In order to improve measure accuracy and broaden the frequency range, a frequency measure system of two-channel signal based on PSoC is proposed. The core processing unit of this system is CY8C29666. Based on the synchronous multi-cycle frequency measurement, and combined with the advantages of high integration, resourceful, flexible configuration and anti-jamming stability PSoC chips, the system performed high accuracy frequency measure of two-channel signal between 0.1 Hz~10M Hz. Based on the results, the measure accuracy is analyzed. |
