Question

an asynchronous 4 - bit binary down counter changes from count 2 to count 3. how many transitional states are required?

Explanation:

Step1: Convert decimal to binary

2 in binary is 0010, 3 in binary is 0011 for a 4 - bit system.

Step2: Analyze transition

For an asynchronous 4 - bit binary down - counter going from 0010 to 0011, it first goes from 0010 to 0001 (1 transitional state), then from 0001 to 0011 (1 transitional state). In total, 2 transitional states are required.

Answer:

2
