The explanation and use of timing diagrams used in digital electronics to graphically show the operation of various circuits are given.

In this animated object, learners examine the switch settings for the on-delay, off-delay, and one-shot timing functions of an optical sensor. A brief quiz completes the activity.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.
