| Abstract: | The principle of phase measurement and detection is discussed. The scheme of measuring phase based on FPGA is presented. Dual-chip system from FPGA and single-chip computer fulfils the phase measurement with equivalent accuracy and constant error. This system, having a wide measurement range of signal frequency an d the small error in measuring phase, is of great value to practical application. |
