Easy way to remember logic gates?

I wonder if this is the right forum to ask this question in.<BR><BR>Anyways, today in class we went over logic gates: AND, OR, XOR, and NOT. Now, I can remember AND and NOT but not OR and XOR. AND is ...

A digital technique eliminates the need for an analog multiplier

Traditionally, multiplying two analog signals involves the use of analog multipliers. Design engineers digitize analog signals using an analog-to-digital converter (ADC) and then run the code on a ...
