Analyzing PWM Period and Duty Cycle without an Oscilloscope 

Now that I have an oscilloscope, I’ve been able to learn a lot more about the circuit I’ve been designing for the MC-2100, as well as the MC-2100 itself. However, a lot of people don’t have access to a scope (even one as old and crappy as mine :)). I’ve had an idea for a method of analyzing a PWM signal without a scope for a while now. Last night, I got some time to test my idea and it worked fairly well, so I figured I’d share it here.
