I like to use that example because the motor in a drill that plugs into the wall creates a lot of electrical noise, both conducted along the power cord to the AC outlet and into the TV set, and radiated through the air to the TV set. The result is a seriously messed-up picture.

Because products must be tested to prove that they meet the regulatory requirements [u]before[/u] they can be marketed, we can't talk about what we've been working on. If the product happens to have military applications, the need for discretion becomes imperative.

A knowledge of physics helps you to understand what goes on during the tests we perform, and why. You could learn about what we do from scratch, but it would be harder to grasp.
