GATE EC 2022:Digital Circuits Quiz 1 (App update required to attempt this test)

Find size of ROM (in bits) to implement Dual 4 – line to 1 – line MUX with common selection inputs

Consider the arithmetic operation shown below with base ‘r’ then find the value of r.

(55)_r + (12)_r + (31)_r = (142)_r

If X₁ and X₂ are the inputs to the circuit shown below, the output Q?

A Mealy system produces a 1 output if the input has been ‘0’ for atleast by two consecutive clocks followed immediately by two consecutive 1’s. Then find minimum no. of states of system (S) and minimum number flip flops required (F).
