Robots with a Vision

In M1’s IR sensor array, each LED is
fired in turn and detected reflections are latched by
the 74HC259 into an eight-bit byte.

Machine chine vision is a field of electrical engineering that’s changing how we interact with our environment, as well as the ways by which machines communicate with each other. Circuit Cellar has been publishing articles on the subject since the … Continue reading

How-To Guide for Timing Analysis

Photo 1: I used Timing Diagrammer Pro for the timing analysis of the simplified digital circuit. Note that the gray areas on the waveform denote regions of uncertainty. The red areas show a timing violation.

Although many young engineers have been taught excellent circuit design techniques, most haven’t been schooled about the importance of timing analysis. What is timing analysis? Why is timing analysis important? How do you perform timing analysis? Philip Nowe’s Circuit Cellar … Continue reading
