Digital Circuit and Microprocessor MCQs

Decimal 43 in Hexadecimal and BCD number system is respectively

The Boolean function f implemented in the rgure 7.28 using two input multiplexers is

The present output Qn of an edge triggered JK flip-flop is logic 0. If J = I, then Q0+1

Statement for Linked Answer Questions 81a and 81b :Consider an 8085 microprocessor system1 The following program starts at location 0100H. LXI SP, ()OFF ;LXI H, 0701;MVI A, 20H;51JB M The content of accumulator when the program counter reaches 0109H is

IL If in addition following code exists from 019H onwards,ORI 40 H;ADDM What will be the result in the accumulator after the last instruction is executed?

A new Binary Coded Pentary (BCP) number system is proposed in which every digit of a base-5 number is represented by tis corresponding 3-bit binary code. For example, the base-5 number 24 will be represented by its BCP code 010100. In this numbering system, the BCP code 100010011001 corresponds to the following number in base-5 system

Following is the segment of a 8085 assembly language program LXI SP, EFFFH CALL 3000 H;3000 H: LXI H,3CF4 H;PUSH PSW

X = 01110 and Y = 11001 are two 5-bit binary numbers represented in two's complement format. The sum of X and Y represented in two's complement format using 6 bits is

The Boolean function Y = AB + CD is to be realized using only 2- in put NAND gates. The minimum number of gates required is
