Discrete Time Signal Processing

By Prof. Mrityunjoy Chakraborty | IIT Kharagpur

Learners enrolled: 1436

This course can in short be called ``DSP revisited”. It is seen that even though DSP is taught as part of UG curriculum in all engineering colleges, often the concepts are not taught very well, leading to huge gaps in understanding of the basics. The purpose of this course is to provide a guided tour of the key issues of DSP where every effort will be made to reinforce the basic concepts involved. Towards this, many new aspects and interpretations will be presented that are usually not covered in books.

INTENDED AUDIENCE : Academic and Industrial Professionals, Core Course, UG & (PG students can take it as a refresher course), B.Tech/M.Tech

PREREQUISITES : None (some background in signals and systems might help though)

INDUSTRY SUPPORT : Industries working in communications, speech and audio processing, instrumentation etc.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
