The Coursera course ‘Processamento Digital de Sinais – Amostragem’ offers an in-depth exploration into one of the most fundamental concepts in digital signal processing: sampling. This course is ideal for students, engineers, and tech enthusiasts interested in understanding how analog signals like music and images are captured and processed in digital devices.
The course starts with a solid introduction, setting the stage for the complex topics to follow. It then delves into the nature of continuous and discrete sine waves, providing essential background on how signals can be represented as combinations of sinusoids. This foundational knowledge is crucial for grasping the subsequent topics.
The core of the course focuses on sampling, explaining how an analog signal is converted into its digital counterpart. Students learn about the challenges of aliasing and how to mitigate its effects through proper system design. The course also covers the reconstruction process, detailing how digital signals are converted back to analog form, and how to minimize distortions using filters.
A highlight of this course is the discussion of the sampling theorem, emphasizing that with appropriate sampling rates and filtering, perfect recovery of the original signal is possible. This fundamental principle underpins many modern digital systems and technologies.
Overall, I highly recommend this course to anyone interested in digital signal processing, whether you are a student, a professional working in signal-related fields, or a hobbyist eager to understand the digital world better. The course combines clear explanations with practical insights, making complex concepts accessible and engaging.
