Digital Signal Processing

Digital Signal Processing is an area of electrical engineering. Computers are used to gain information that useful signals contain. These Signals are important for a broad range of applications: communications, medicine, geology, consumer electronics, road transport and aviation, industrial production, to name just a few. In most cases these signals originate as sensory data from the real world. The analog-to-digital converter turns them to the digital format and handles them over to the Digital Signal Processor (DSP). A DSP is a specialized microprocessor optimized for the fast mathematically processing in the signal-analysis. Each area of electrical engineering has developed its own methods and algorithms in using Digital Signal Processing in order to reach their desired goals. These might be filtering of information, recognition of pattern, enhancement of video- and audio material, generating of signals, spectrum analysis …
