how to find time period in case of MOD-n  counters .

@Dharmendra Lodhi

did you mean, output clock, time period?

then it is n* i/p clock period

Answer 1

First, we have to find the frequency of the clock. Using the formula f = 1 / (n * T_pd ) we get the frequency. i.e., 2 MHz.

Now, the circuit acts as a MOD-2 counter. So, the output frequency is f/2 i.e., 1 MHz.
