This paper introduces a design scheme of high-precision digital frequency meter based on synchronous frequency measurement method. We select Cypress PsoC1 Cy8C29466 as its core component, the whole design is flexible and simple, has very few peripheral devices and a high reliability. And meanwhile, we realize equal precision measurement of signals in different frequency ranges by sectional frequency measurement method.
