4 Bit Comparator Logic Diagram. Figure 24 logic diagram for a 4 bit comparator in order to reduce the area we can still decrease the number of gates. 2 logic design for 4 bit comparator 21 logic design procedure magnitude comparator is a combinational circuit that compares two numbers and determines their relative magnitude.
Exclusive or comparator and nand or nor plus 10 more here is the logic diagram. 4 bit comparator easyeda. A comparator is shown as figure 21.
The open drain output ab should be used with an external.
It consists of four inputs and one output to generate an equal or unequal result between the two binary numbers. The logic diagram of the 4 bit magnitude comparator is shown in the below diagram. And here is the logic gates diagram for this circuit. Figure 25 optimized logic diagram for a 4bit comparator seeing from the above diagram we can use 11 gates to implement the 4 bit comparator beside the inverters.
