PURPOSE:To detect coincidence between input data with a simple circuit by using the signal of XNOR between two data in a synchronous full adder/ subtractor. CONSTITUTION:A signal S' is obtained by operating XNOR between input data A and B; and since this circuit is a dynamic operation ...
Twitter Google Share on Facebook full adder Acronyms [¦fu̇l ′ad·ər] (electronics) A logic element which operates on two binary digits and a carry digit from a preceding stage, producing as output a sum digit and a new carry digit. Also known as three-input adder. ...
Then we propose a quaternary quantum reversible full adder and a quaternary quantum parallel adder circuit. In addition, we propose a quaternary quantum reversible parallel adder/subtractor circuit. The proposed designs are compared with existing designs and improvements in terms of hardware complexity, ...
Digital circuits are implemented in QCA using majority logic. Adder and subtractor are used widely in almost every data processing system. For efficient hardware implementation, a single hardware can be used to perform both addition as well as subtraction. In this paper, a novel majority logic ...
The full-adder is a building block for many more complex digital circuits like ripple carry adders, carry look-ahead adders, and subtractors.
Generally, the full subtractor is one of the most used andessential combinational logic circuits. It is a basic electronic device, used to perform subtraction of two binary numbers. In the earlier article, already we have given the basic theory ofhalf adder & a full adderwhich uses the binary...
Hence, Logic circuit diagram for Half-Adder can be drawn as,What is a Full Subtractor?Full Subtractor also belongs to the class of a combinational circuit and is used to perform subtraction of two binary bits. The half-subtractor can only be used for subtraction of LSB bits, but if there...
Erratum: Method of implementation of frequency encoded all optical half adder, half subtractor and full adder based on semiconductor optical amplifiers and... A novel frequency encoded all optical half adder, half subtractor and full adder are proposed. The implementation is ultrafast one and the fr...
A full-subtractor is a combinational logic circuit that performs subtraction using inputs of three binary digits: one minuend and two subtrahends, and considers eight input states: (0,0,0), (0,1,0), (1,0,0), (1,1,0), (0,0,1), (0,1,1), (1,0,1), and (1,1,1). ...
SubtractorQuantum-dot Cellular automata is a promising area to implement digital systems at nano scale level. Adders and subtractors are widely used in almost every digital information processing system. This work targets to design an efficient 8-bit adder/subtractor that can perform addition as ...
