In signal processing, delay equalization corresponds to adjusting the relative phases of different frequencies to achieve a constant group delay, using by adding an all-pass filter in series with an uncompensated filter. Clever machine-learning techniques are now being applied to the design of such filters.
A group delay equalization circuit, automatic equalization system and method
The application discloses a group time delay equalization circuit, an automatic equalization system and method, the group time delay equalization circuit comprises an adjustable group time delay equalizer in a single-stage structure or a multi-stage cascade; the group time delay automatic equalization system comprises a frequency conversion channel to be optimized, a vector network analyzer to test a group time delay, a group time delay equalizer, a host computer and control software; after the final target group time delay fluctuation parameter of the frequency conversion channel is determined, the initial parameters of the frequency conversion channel and the group time delay equalizer are tested, and the control voltage of the group time delay equalizer is adjusted in cooperation with the control software, so that the group time delay fluctuation of the frequency conversion channel and the group time delay equalizer in cascade satisfies the target requirement, and the application has great flexibility and practicality.
