This lecture, published by Columbia Gorge Community College, provides an overview of oscilloscopes. The instructor shows how to "vertically and horizontally scale, position, trigger, couple, and attenuate a voltage signal for display and measurement purposes." The recording runs 19:25 minutes in...

This video, published by Columbia Gorge Community College, is the first part of a two part lecture that discusses pneumatic systems through comparison with hydraulic systems, including a particular focus on the differences between compressible and incompressible fluids. The first part of the lecture...
