Introduction When designing digital systems, especially for the first time, such as calculators, computers, and communication devices, we often start with complex Boolean expressions that involve several variables and gates. These expressions can be simplified using specific techniques later, allowing the same logical function to be performed using fewer gates Read more…
History The concept of flip-flops dates back to the early days of electronics. The idea behind bistable circuits (flip-flop) dates back to early 20th-century electronics. The first practical bistable multivibrator flip-flop circuit was invented by William Eccles and F. W. Jordan in 1918, and it was called the Eccles–Jordan trigger Read more…
Introduction Adder is a very good example of Combinational Logic Circuits. Definition An adder is a fundamental component in digital electronics devices and is used to perform arithmetic operations, specifically addition. Characteristics Adders are found in the ALU of the CPU. Adders do not have their memory. Their output depends Read more…
Introduction PLA stands for Programmable Logic Array.
