How to calculate frequency with clock signal is 500ps in digital logic?

Question

How can i calculate frequency if clock signal 500ps.

I know the only formula, that is T=1/f

But i cant able to calculate, can anyone help me?

Thanks in advance.

Answer 1

$1$ pico second (ps) is $1 \times 10^{-12}$ seconds, so if the time between pulses is $500$ps this is $500 \times 10^{-12}=5\times 10^{-10} $ seconds.

Then the frequency is $f=1/T=1/(5\times 10^{-10})=0.2 \times 10^{10}=2 \times 10^9=2 \rm{GHz}$
