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電路原理分析uck變換器：也稱降壓式變換器，是一種輸出電壓小于輸入電壓的單管不隔離直流變換器。 圖中，Q為開關(guān)管，其驅(qū)動(dòng)電壓一般為PWM(Pulse、width、modulation脈寬調(diào)制)信號(hào)，信號(hào)周期為Ts，則信號(hào)頻率為f=1/Ts，導(dǎo)通時(shí)間為Ton，關(guān)斷時(shí)間為Toff，則周期Ts=Ton+Toff，占空比Dy=、Ton/Ts。 Boost變換器：也稱升壓式變換器，是一種輸出電壓高于輸入電壓的單管不隔離直流變換器。 開關(guān)管Q也為PWM控制方式，但最大占空比Dy必須限制，不允許在Dy=1的狀態(tài)下工作。電感Lf在輸入側(cè)，稱為升壓電感。Boost變換器也有CCM和DCM兩種工作方式 Buck/Boost變換器：也稱升降壓式變換器，是一種輸出電壓既可低于也可高于輸入電壓的單管不隔離直流變換器，但其輸出電壓的極性與輸入電壓相反。Buck/Boost變換器可看做是Buck變換器和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.
