How Do I Use Digilent Products at School? (Digital Edition)
As you learned from my previous post (the Analog Edition version of this post), we used the Analog Parts Kit and Analog Discovery in EE352 at Washington State University (WSU) to make an AM radio transmitter and receiver. Not only do we use Digilent products in EE352, but we also used Digilent parts in EE324 (Fundamentals of Digital Systems) — the digital lab class I was taking.

Pulse-Width Modulation
Pulse-width modulation (PWM) is a technique that takes advantage an electronic device’s capability to rapidly “pulse” one of its digital pins between logic high and logic low voltage states. The idea is that the switching between the two voltage states in a desired pattern will produce an “average” voltage somewhere between the high and low voltage inputs. If, within a given period, the pin is at a high voltage level more often than a low one, an overall higher voltage (but less than the full strength input voltage) will be observed.
