Logic Gates
The word “discrete” means individual or distinct. In engineering, a “discrete” variable or measurement refers to a true-or-false condition. Thus, a discrete control system is one designed to operate on
How a Gate Works ?
On the previous article, we saw how the output of a gate goes HIGH or LOW according to the voltage level on the inputs. But how is a gate used in a
Digital Building Blocks – GATES
GATES are DIGITAL BUILDING BLOCKS. They are called DIGITAL because they operate on digital principles. They require a signal (also called a PULSE or INPUT) that is either 0v (LOW)
