A 22-MHz clock signal is put into a MOD-16 counter. What is the frequency of the Q output of each stage of the counter?
Q1 = 22 MHz, Q2 = 11 MHz, Q3 = 5.5 MHz, Q4 = 2.75 MHz
Q1 = 11 MHz, Q2 = 5.5 MHz, Q3 = 2.75 MHz, Q4 = 1.375 MHz
Q1 = 11 MHz, Q2 = 11 MHz, Q3 = 11 MHz, Q4 = 11 MHz
Q1 = 22 MHz, Q2 = 22 MHz, Q3 = 22 MHz, Q4 = 22 MHz
