Abstract

The present invention relates to a detection method and system for a power amplifier, wherein the method includes playing a plurality of original signals with different intensities, and obtaining a plurality of test signals, wherein the plurality of test signals are processed by a power amplifier for a plurality of the original signals Obtaining, wherein, one of the test signals corresponds to the original signal of one strength, the corresponding first frequency response curve is obtained for each original signal, and the second frequency response curve is obtained according to the test signal corresponding to the original signal, A plurality of curve groups having the first frequency response curve and the second frequency response curve are formed, and it is determined whether the power amplifier performs gain control on the original signal according to the plurality of curve groups. That is, multiple original signals with different intensities are used to detect the performance of the power amplifier, so that the accuracy of power amplifier selection can be improved, and the playback sound quality of the mobile terminal can be improved.

Description

technical field [0001] The invention relates to the technical field of original external amplifiers, in particular to a detection method and system of a power amplifier. Background technique [0002] With the increasingly common use of electronic equipment, more and more manufacturers have invested in the R&D and manufacturing of electronic equipment. With the escalation of competition, the quality of electronic equipment is also getting higher and higher. Among them, since the performance of the power amplifier in the electronic device directly affects the user's experience of the voice transmission of the electronic device, it is particularly important to test the performance of the power amplifier in the electronic device in advance in the device selection stage. [0003] Generally, manufacturers use a single large signal to test the power amplifier, resulting in inaccurate test results. SUMMARY OF THE INVENTION [0004] The present application provides a detection me...
