Choose the letter of the best answer in each questions. Sequential Logic Circuits - MCQs with answers Q1. High. For an XOR gate having A,B as inputs and Y as output mark the incorrect entry . Infinite. Next . Acceptance of n-different inputs C. Generation of 'm' different outputs as per the required level Hence, statement-5 is correct. There are basically, two types of Sequential Circuit, one is synchronous and the other is Asynchronous Sequential circuit. Synchronous Sequential Logic Circuit is the one in which the output is … The memory elements are devices capable of storing binary information within them.The binary information stored in the memory elements at any given time defines the state of the sequential circuit. A register is defined as _____ a) The group of latches for storing one bit of information b) The group of latches for storing n-bit of information c) The … Which of the following gates give output 1, if and only if at least one input is 1? 6) Which is the correct sequential order of operational steps executed in the combinational logic circuits? B. Reason (R): In an asynchronous circuit, events can occur after one event is completed and there is no need to wait for a clock pulse. In case of Short Circuit,_______Current will flow in the Circuit. Description This mock test of Sequential Logic Circuits - 1 for GATE helps you for every GATE entrance exam. The Flip Flop used here is a Positive edge triggered D Flip Flop, which means that only at the "rising edge of the clock" flip flop will capture the input provided at D and accordingly give the output at Q.And at other times of the clock the output doesn't change.
