1. The problem statement, all variables and given/known data How many flip flops are in a 16bit counter? its actually an interview question, not homework per se. 2. Relevant equations none 3. The attempt at a solution I thought it was 4 since we have 2 inputs from 4 flip flops giving us 2^4 = 16 ? however i'm told that its essentially just made up with 2 flip flops. How is this possible?
