Signal Processing Techniques And Its Applications

Indian Institute of Technology, Kharagpur and NPTEL via Swayam


Digital Signal Processing (DSP) is concerned with the representation, transformation and manipulation of signals on a computer. After half a century advances, DSP has become an important field, and has penetrated a wide range of application systems, such as consumer electronics, digital communications, medical imaging and so on. With the dramatic increase of the processing capability of signal processing microprocessors, it is the expectation that the importance and role of DSP is to accelerate and expand.PRE-REQUISITE: NillINTENDED AUDIENCE:UG and PG student of Electronics and Electrical Communication Engg, Electrical Engineering and Computer Science and Engineering along with Industry working in the area of Image and speech processingINDUSRTY SUPPORT:Nill
