colorAutoCorrelogram

Histogram equalization. Is a method in image processing of contrast adjustment using the image s histogram. This method increase the contrast of the example s image, because it s a image represented by close contrast values.

各种干扰信号,包括噪声调频干扰,噪声调相干扰,噪声调幅干扰,射频噪声干扰(A variety of interfering signals, including noise FM interference, noise, phase modulation, interference, noise AM interference, RF noise)

CMMB中PN序列的生成和强自相关特性在各种条件下的保持(The reasearch of PN sequences in CMMB, about its autocorrelation)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)
