Filtering: Extracting What We Want from What We Have

Educational Use
Rating
0.0 stars

Filtering is the process of removing or separating the unwanted part of a mixture. In signal processing, filtering is specifically used to remove or extract part of a signal, and this can be accomplished using an analog circuit or a digital device (such as a computer). In this lesson, students learn the impact filtering can have on different types of signals, the concepts of frequency and spectrum, and the connections these topics have to real-world signals such as musical signals. Students also learn the roles that these concepts play in designing different types of filters. The lesson content prepares students for the associated activity in which they use an online demo and a variety of filters to identify the message in a distress signal heavily corrupted by noise.

Rating
0.0 stars

Students learn the basic principles of filtering as well as how to apply digital filters to extract part of an audio signal by using an interactive online demo website. They apply this knowledge in order to isolate a voice recording from a heavily noise-contaminated sound wave. After completing the associated lesson, expect students to be able to attempt (and many successfully finish) this activity with minimal help from the instructor.

Virtual Oscilloscope

Rating
0.0 stars

The Virtual Oscilloscope replicates a real, physical oscilloscope, including having live sound input on browsers that support it. It can also be embedded on any web page. The tool enables learners to become comfortable with using an oscilloscope in their own time. Oscilloscopes are expensive, niche pieces of equipment and this free online tool completely lowers the barrier for learners to get to grips with how they behave and function.
