this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic circuits directly, a much more versatile solution was to ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left somewhat ...

Also known as "combinatorial logic," it ... made of primitive logic gates (AND, OR, NOT, etc.) in which all outputs of the function are directly related to the current combination of values ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

Here, the output Q is 1 (TRUE) only if inputs C and D are 1 (TRUE). D is only 1 (TRUE) if inputs A and B are 1 (TRUE).

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of ...
