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

Standard Operating Procedures Radiology 1. PURPOSE: a. To provide maximum quality radiographs in an efficient amount of time. b. To establish responsibilities‚ procedures‚ policies‚ and techniques which prevent excessive radiation exposure to patients and staff. c. To set guidelines to be followed for checking radiology systems performance and maintaining optimum image quality and equipment safety for the technologist who operate these systems and the patients as well

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

nature of digital signals‚ binary‚ and other multi-level signal types do require an explanation of the two most prominent telecommunications types that exist‚ and examples of how they are applicable to specific devices‚ the binary is association and its function. (Please note that the majority of the information below are extracts from various websites‚ used to validate and support a theoretical premise; on which an understanding of multilevel signals exist. ) Analog and Digital Signals

imaging are advancing technologically every year‚ the workload is escalating and also sometime leads to workforce shortage due to poor management and not having a proper strategy in place. (Lau‚ 2009). Most hospitals have now changed to digital or computed radiography‚ which are much faster imaging modalities as compared to the traditional conventional film and paper imaging. These hospitals can increase their patient throughput by simply improving their operation rather then to increase its physical

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

OBSERVATION The modicom 1 board‚ first in my observation is the power input these are the electrical input connections necessary to power the module. The LJ Technical Systems’ "I.C. 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
