Abstract :
Based on a digital phase ramp feedback technique, a new type of all digital closed loop FOG detection scheme is introduced. After a detailed analysis of its principles and design, a complete FOG signal detection system is developed and set-up. Experiments and tests show that the scheme can solve problems such as scale factor error and dynamic range effectively.
