Digital Signal Processing is the branch of engineering that, in the space of just a few decades, has enabled unprecedented levels of interpersonal communication and of on-demand entertainment. By reworking the principles of electronics, telecommunication and computer science into a unifying paradigm, DSP is a the heart of the digital revolution that brought us CDs, DVDs, MP3 players, mobile phones and countless other devices.

The goal, for students of this course, will be to learn the fundamentals of Digital Signal Processing from the ground up. Starting from the basic definition of a discrete-time signal, we will work our way through Fourier analysis, filter design, sampling, interpolation and quantization to build a DSP toolset complete enough to analyze a practical communication system in detail. Hands-on examples and demonstration will be routinely used to close the gap between theory and practice.

To make the best of this class, it is recommended that you are proficient in basic calculus and linear algebra; several programming examples will be provided in the form of Python notebooks but you can use your favorite programming language to test the algorithms described in the course.

Reviews summary

Informative signal processing course

Learners say this course is a well-made and informative introduction to digital signal processing with engaging assignments. Some learners found the course challenging, especially the difficult exams and assignment problems. However, most learners agree that they learned a lot from the image processing material and engaging assignments.
Engaging image processing lectures.
"A nice "treat" after all the abstract theory."
"Found the image processing material more interesting than I expected."
Quizzes rely on unclear assumptions.
"My biggest gripe (which was true for the rest of the courses in the specialization) is that the quizzes often relied on inferences or assumptions that were either not covered in the lectures or not clarified in the questions."
Exams and problem sets are difficult.
"Fraud course. Tells wrong answers as correct ones."
"Questions are too much tough to solve that it became so much frustrating."
