Abstract

Abstract:

This paper describes the method for designing a high-resolution frequency meter based on the DDS (Direct Digital Synthesizer) using a simple circuit. In this method, DDS is used to track the value of the measured frequency and synthesizes automatically appropriate frequency standard signals. This method is applicable to measuring signals within a wide range of frequency. Prototype measured data show that the high-resolution frequency meter can reach the magnitude of 10^-12/s.

Key words: DDS, high-resolution, frequency meter, frequency measurement
