Abstract
The invention relates to a method of synthesizing the color-changing noise, which comprises the following steps: collecting target digital signals or target digital signal traces to be subject to the noise-adding processing; generating white noise signals or white noise signal traces; performing a convolution operation on the target digital signals and the white noise signals to generate color-changing noise signals or performing a convolution operation on the target digital signal traces and the white noise signal traces to generate color-changing noise signal traces. In addition, the invention also relates to a method and device for performing simulating and noise-adding processing using the color-changing noise.
