Basic Logic Gates Using NAND Gate

This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

Using isolated ADCs and an XNOR logic gate as a multiplier to measure active power

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...

Using Pulleys And Weights To Explain Binary Logic Gates

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (Wikipedia) ...

Using cancer cells as logic gates to determine what makes them move

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate. Cancer cells ...
