It full USES of DSP chips for high speed and the advantages of command and MATLAB powerful numerical analysis, signal processing and graphics capabilities to calculate voltage flicker value.

Based on effect of the impedance Angle value size in flicker calculation formula, an engineering estimation method of impedance Angle for flicker calculation is presented in this paper.

The colorful flicker piece is a kind of very soft and thin piece with metal luster. The fabric printed with colorful flicker pieces can obtain special and flash effect and higher value added.
