From Gates To FPGA’s – Part 1: Basic Logic

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

Boolean operators and truth tables

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 True or ...

From light to logic: First complete logic gate achieved in soft material using light alone

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

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 ...
