GO Classes Test Series 2023 | Digital Logic | Test 2 | Question: 16
A priority encoder is an encoder circuit that includes the priority function. The operation of the priority encoder is such that if two or more inputs are equal to $1$ at the same time, the input having highest priority will take precedence. In a $4$-bit priority ... $x=D_{2}+D_{3}, y=D_{3}+D_{1} D_{2}^{\prime}$

GO Classes Test Series 2023 | Digital Logic | Test 2 | Question: 23
Assume you need a $64$-to-$1$ multiplexer controlled by $6$ select signals $A$ through $F,$ i.e., a binary number $ABCDEF$ specifies the index of the input to be sent to the output. However, as we assume a logic gate can not have more than ... of $X_{1} Y_{1} X_{2} Y_{2} X_{3} Y_{3}$ should be $011011$ $110110$ $111001$ $100111$
