What would be the output frequency of a three stage [three flip flop] frequency division circuit with an input clock frequency of 80 kHz?

Question 1 options:

A) 100 kHz
B) 20 kHz
C) 15 kHz
D) 10 kHz
E) 5 kHz
F) 1 kHz

Respuesta :

Answer:

Option E

10 kHz

Explanation:

[tex]F_o=\frac {F_i}{2^{N}}[/tex]

Where [tex]F_o[/tex] is output frequency, [tex]F_i[/tex] is input frequency and N is the number of flip-floop

Substituting 80 kHz for [tex]F_i[/tex] and 3 for N we obtain

[tex]F_o=\frac {80 kHz}{2^{3}}=10 kHz[/tex]

Therefore, the output frequency is equivalent to 10 kHz
