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 by changing the

compared to a Conventional Data Processing (CDPS) There are three main features of a database management system that make it attractive to use a DBMS in preference to more conventional software. These features are centralized data management‚ data independence‚ and systems integration In a database system‚ the data is managed by the DBMS and all access to the data is through the DBMS providing a key to effective data processing. This contrasts with conventional data processing systems where each application

Use case diagram A use case diagram at its simplest is a representation of a user’s interaction with the system that shows the relationship between the user and the different use cases in which the user is involved. A use case diagram can identify the different types of users of a system. The different use cases and will often be accompanied by other types of diagrams as well.

firm and each of its plants. Three categories of capability include technological processing capability‚ physical size and weight‚ and production capacity. ____________________________________________________________ _________ 4. How does a shaping process differ from a surface processing operation? Answer. A shaping process changes the geometry of the work material (machining or forging). A surface processing operation does not alter the geometry‚ but instead alters the properties and/or

How does photosynthesis impact the flow of energy and the cycling of nutrients‚ you ask? Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis provides the base for the one way flow of energy through the biosphere. Plants convert energy from the sun into sugars‚ which provide fuel for themselves and for other organisms. Photosynthesis also cycles carbon and oxygen nutrients through the

It then sends that information to the monitor through a cable. Creating an image out of binary data is a demanding process. To make a 3-D image‚ the graphics card first creates a wire frame out of straight lines. Then‚ it rasterizes the image (fills in the remaining pixels). It also adds lighting‚ texture and color. For fast-paced games‚ the computer has to go through this process about sixty times per second. Without a graphics card to perform the necessary calculations‚ the workload would be too
