GATE 2024 Digital Circuits Foundation Quiz 27

How many 1’s are present in the binary representation of (4*4096)+(9*256)+(7*16)+(5)?

The initial output of the following circuit is 1. If we apply 010101 at input A (first bit is zero), then what is the bit pattern generated at the output Y.

Consider the following statements.

S1: All output bits are high in an active high output decoder when it is disabled.

S2: All output bits are low in an active low output decoder when it is disabled.

S3: All output bits are low in an active high output decoder when it is disabled.

S4: All types of decoders are used to produce only one bit difference at output in their enabled condition.

Which of the above statements are correct?

An input frequency of 12KHz is applied to the JK Flip-Flop arrangement shown in the given figure.

The frequency at output is _____ KHz
