Logic Design covers binary numbers, logic gates, multiplexors and more. In this video we go over binary numbers and basic logic gates (AND, OR). There are also other gates such as NOT, NOR, NAND, and XOR which we will be covered in future tutorials.
Binary numbers are only made up of 1's and 0's, representing on and off, true and false, heaven and hell, or however else you like to think of it (JK about the heaven and hell). Counting in binary from 0 to 4 looks like:
