Answer: Digital Signal Processing (DSP) is the analysis and representation of discrete-time signal systems, including discrete-time convolution, difference equations, the z-transform, and the discrete-time Fourier transofrm.

The main applications of DSP are in the fields like biomedicine, seismology, digital communications, SONAR, RADAR, speech processing, video compression, digital image processing, audio compressing and audio signal processing. Some of the examples are transmission and speech compression in forecasting seismic data processing, weather forecasting, sound reinforcement applications, room correction of sound in hi-fi, mobile phones, etc…

For this you need to be ready with C, C++, Assembly Level Programming, Signal Processing Algorithms and Time Procesing. According to NASSCOM, there would be higher growth prospects in the coming days. Many prominent private companies like Intel, Analog Devices, Lucent, Motorola and Texam instruments are strongly venturing into this field with high potential.

You can also find government jobs in Police Department, All India Radio, Doordarshan, BSNL, Army Signal Core, etc.. You can watch free videos on Digital Signal Processing from http://nptel.iitm.ac.in/video.php?subjectId=117102060 and http://ocw.mit.edu/resources/res-6-008-digital-signal-processing-spring-2011/index.htm

Sir, I have completed my engineering in the stream of ECE with 84% am in search of a job. Now I want to do .NET course to enter in to IT field. please suggest me relevant courses to be done.

Answer: First you must get clarity on what you want to do. If you really interested in IT field, then evaluate yourself to identify whether you are good / interested in analysing the situations, coding, testing, etc. Never join such street side institutions just because of someone in your network joined that course. Coursera (https://www.coursera.org/) offers world’s best courses, online, for free. Think of domain and choose as per your interest.

For example, if you are interested banking application development, think of a customer requirement and try to develop small products on your own and discuss the same with your friends / experts. There are many technical forums where you can get answer from like minded programmers. Also you can use Quora (http://www.quora.com/) to get expert/other’s opinion on the doubts you have.
