Question

How to solve this?

Q. 12 Two counter circuits, counter-1 and counter-2 are shown below with their clock frequencies as 80 kHz and 40kHz respectively

Counter 1

Counter 2
If $f_{1}$ and $f_{2}$ are frequencies at outputs $Q_{2}$ and $Q_{5}$ respectively, then what is the value of $\left(f_{1} / f_{2}\right)$ ?

Answer 1

Since, they have synchronous counters, same clock frequency will reach to every FFs. So, basically 80 kHz will be sent to D2, and the frequency will reduce by half at output f1. So, f1 = 80/2 = 40kHz. Similarly, f2 = 40/2 = 20 kHz.

So, f1/f2 = 40/20 = 2

Comments

how 2KHz when devided two frequency value plz correct it

yes it should be only 2, no unit. Thank you
