In this code of LSB steganography the first three bit of message image is extracted and hidden in the cover image.At receiving the bit is extracted and message is shown.

说明：  为了采集准确的心电信号，设计了一套基于瞬时心率信号抗干扰测量的方法，针对微弱并易受干扰的心电采样信号，进行有效地硬件以及软件滤波，通过软件数字滤波算法，得到真实的心率信号(Set based on the instantaneous heart rate signal immunity measuring method to collect accurate ECG, ECG sampling signal for the weak and vulnerable to interference, hardware and software filtering, digital filtering algorithm through software, get real The heart rate signal)

是美国统计学家萨尔斯伯格以“女士品茶问题”为切入点所著的一部关于统计学历史与变革的书，以一种全新的视角带领读者进入统计学的世界，体会统计学带给哲学观、宇宙观的变革(Salthe Berg statistician USA to Lady Tasting Tea problem as the starting point of a statistical history and change of the book, with a new view and lead the reader into the world of experience of statistics, statistics to philosophy, cosmic view change)

线性时不变离散时间系统的频域分析传输函数和频率响应，(Linear time-invariant discrete-time system transfer function and frequency domain analysis of frequency response,)

1.why there is a spike at every peak of current wave form? how to eliminate this? 2.actual current before filtering is around 6 amps peak , but after filtering it is giving 8.5 amps ,even after changing KP,KI values in PI controller reference value is not coming down...
