  1. The transform uses the scale of the signal to decompose and make self - adapting frequency band partition of the input signals. therefore the amplitude value and the modulating frequency of the flickering signal can be obtained. with the instantaneous frequency in this method, the present study also analyzes the signal in terms of both time and frequency, and thus gets the time at which the flickering signal occurs and terminates
