What is the purpose of the Gray code in digital systems?

To complicate the representation of binary numbers

To speed up the digital inputs in a circuit

To represent a sequence of numbers with only one bit changing between successive numbers (correct)

To increase the likelihood of a digital circuit misinterpreting changing inputs

When is the situation more prone to misinterpretation in digital systems?

When the input conditions remain unchanged

When the digital system is running at slow speeds

When only one input condition is changing at a time

When multiple input conditions are changing at the same time (correct)

How many bits must change states at the same time when the three-bit binary number for 3 changes to 4?

Four bits

One bit

All three bits (correct)

Two bits
