Can you define what rectifiers are and their function within a hardware design?

There are several different electronic components you need to incorporate into any hardware design. The interviewer will expect you to be familiar with all of these. You'll need to define what they are, how they function, and how they contribute to the overall design of a piece of equipment. You can prepare for the interview by reviewing the list of components you normally incorporate into your designs and make sure you can address these three questions for each of them.
