Detailed Solution
Download Solution PDFThe correct option is 10.
Concept:
Counters:
- It is a sequential logic circuit that has a clock input signal and a group of output signals
- It represents an integer "counts" value.
- Internally, counters use flip-flops to represent the current counts and to retain the counts between clocks.
- N values can be counted with n number of flip flops. its relation is given by-
where, N = number of counts
n = number of flip flops
Calculation-
Given- N= 4095
Hence total of 12 flip flops are required to count from 0 to 4095.
