This m file hide an image jpeg,png in another jpeg,png image. The height and width of the secret image is in LSB of 1st 32 pixels of 1st row of the cover image.This helps in the recovery of secret image. The secret image must be smaller than cover image.A message box will appear with a number ,that number is the maximum product of width and height of secret image that can be successfully embedded in the cover image. The final png image will appear in workspace with random name.This image contains the secret image.One such png image is in the zip file with name 4447.png it contains an image of res 100x122.

This document explains the pulse compression technique. Why it is required and how can it be used effectively. The pulse compression technique helps to increase the maximum range without sacrificing the range resolution and still the power requirement remains low.

BUCKBOOST电路原理分析uck变换器：也称降压式变换器，是一种输出电压小于输入电压的单管不隔离直流变换器。 图中，Q为开关管，其驱动电压一般为PWM(Pulse、width、modulation脉宽调制)信号，信号周期为Ts，则信号频率为f=1/Ts，导通时间为Ton，关断时间为Toff，则周期Ts=Ton+Toff，占空比Dy=、Ton/Ts。 Boost变换器：也称升压式变换器，是一种输出电压高于输入电压的单管不隔离直流变换器。 开关管Q也为PWM控制方式，但最大占空比Dy必须限制，不允许在Dy=1的状态下工作。电感Lf在输入侧，称为升压电感。Boost变换器也有CCM和DCM两种工作方式 Buck/Boost变换器：也称升降压式变换器，是一种输出电压既可低于也可高于输入电压的单管不隔离直流变换器，但其输出电压的极性与输入电压相反。Buck/Boost变换器可看做是Buck变换器和Bo

The PW2228A is a high efficiency single inductor Buck-Boost converter which can supply theload current up to 1.5A. It provides auto-transition between Buck and Boost Mode. The PW2228Aoperates at 2.4MHz switching frequency in CCM. DC/DC converter operates at Pulse-Skipping Modeat light load. The output voltage is programmable using an external resistor divider, or is fixed to3.3V internally. The load is disconnected from the VIN during shutdown.The PW2228A is available in TDFN3X3-10 package.
