Explanation: there is only 1 sign bit in all the standards. in a 32-bit format, there is 1 sign bit, 8 bits for the exponent and 23 bits for the mantissa.
Explanation: the first bit is the sign bit whereas the
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. because, all the input is compared to each other, therefore it is possible only by using 1 circuit.
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. in a digital comparator, only 3 outputs are possible (i.e. a = b, a > b, a < b). so, a – b is incorrect option.
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. in a digital comparator, only 3 outputs are possible (i.e. a = b, a >b, a < b). other than this, the output will be 0.
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. thus, there are two inputs required for a digital comparator (i.e. a & b).
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. if a > b, it means that it satisfies one of the condition among three. hence the output will be 1.
Explanation: generally, an xnor outputs high for even number of 1s or all 0s and outputs low for otherwise. thus, an xnor gate is a basic comparator, because its output is “1” only if its two input bits are equal.
Explanation: comparators are used in central processing unit (cpus). because all the arithmetic and logical operations are performed in the alu(arithmetic logic unit) part of the cpu.
Explanation: a comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. a circuit that compares two numbers and determine their magnitude is called magnitude comparator.
