Digital Micromirror Device ( Chunhai Ji Introduction The applications of large screen‚ high brightness electronic projection displays include (1) electronic presentations‚ (2) entertainment‚ (3) status and information and (4) simulation (e.g.‚ training‚ and games). So far the electronic presentation market is being driven by the pervasiveness of software that has put sophisticated presentation techniques into the hands of the average PC user. Normally three of projection display techniques

BY nikhil teja DIGITAL SIGNAL PROCESSING A signal is defined as any physical quantity that varies with time‚ space or another independent variable. A system is defined as a physical device that performs an operation on a signal. System is characterized by the type of operation that performs on the signal. Such operations are referred to as signal processing. Advantages of DSP 1. A digital programmable system allows flexibility in reconfiguring the digital signal processing operations

September 23‚ 2014 Reliability of Forensic Tools What’s reliable and what’s not so scientific when it comes to forensic tools? Forensics is relating to the use of science or technology in the investigation and establishment of facts or evidence in a court of law. Forensic tools examples are forensic photography‚ forensic ballistics‚ forensic toxicology‚ computer forensics‚ hair analysis‚ DNA analysis‚ and fingerprint evidence. Forensic tools can be used rhetorically in debate or argument

Construction Digital Voltmeter Raj K. Gorkhali A voltmeter finds its importance wherever voltage is to be measured. Here we present an easyto-build and accurate digital voltmeter that has been designed as a panel meter and can be used in DC power supplies panels or where it is necessary to have an accurate indication of the voltage. Circuit description The circuit uses an analogue-todigital converter ICL7107 made by INTERSIL. Fig. 1 shows the pin detail of IC L7107. This IC incorporates in

Paper What is ethical and unethical regarding digital manipulation of media content that society is exposed to in modern days? There are many theories and beliefs regarding ethics of digital manipulation. Many people are under the impression that digital manipulation began with the invention of Photoshop like imaging software. The truth is that digital manipulation can be dated back to the invention of photography. The argument that digital manipulation is unethical can be supported in many

the digital information era‚ “the Net Generation” has a crazy passion for the new social media communicating platforms--cell phones‚ blogs‚ Facebook‚ Twitter and YouTube. The concerned parents are beset with worries that their kids’ digital immersion has obviously led to their habitual distraction‚ which will directly make an adverse effect on their learning. Vishal Singh‚ the hero of this article‚ is surely an exact example of the “Digital Natives”‚ who are really lured by the digital realm

Digital electronics‚ or digital (electronic) circuits‚ represent signals by discrete bands ofanalog levels‚ rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance‚ signal attenuation or parasitic noise do not leave the discrete envelope‚ and as a result are ignored by signal state sensing circuitry. In most cases the number of these states is two‚ and they are represented by

2012 Chapter 4 Project Summary Project 4-1 In this project I’ve research current acquisition tools. The acquisition tool is a program or hardware device used to read digital source and then create either an image file or a clone of a digital source. There are many tools available today to use for computer forensics. They include both open source and proprietary software. Some of the more common software is ProDiscover‚ SnapBack DatArrest‚ NTI SafeBack‚ DIBS USA Raid‚ ILOOK Investigator IXimager

Power 60" or "System Power 90" is the recommended power supplies. Then second is the sampling control logic is the circuitry generates the timing and control signals that sample the input waveform‚ and also creates a sinusoidal 1 kHz signal for use during the MODICOM 1 practical exercises. It is recommended that this
