Hi Vikram,

It is the relation between i/p clk signal and o/p signal that is required.

Wrt attachment, let's say i/p clk is Fin and and output signal is Fout ,

then Fout = (?) Fin

We need to find the relation ( ? mark as above)..

Thanks,

Re: Digital Question

Well Vikram,
I think the difference is not in Frequency, The difference b/w ip and op is the delay which causes DFF.

Re: Digital Question

Answer is
Fout = 3/2 fin

Re: Digital Question

Hi all,

I tried to work it out, and found that Fout = (1/2) Fin with duty cycle =25%. I still not sure about it. If have any comments then plz post

Thanks,

Re: Digital Question

hi,
easiest and most realiable check is: compile & simulate your example

Re: Digital Question

Looking at J_andr's post , I can say that Fout = (3/2) Fin. Thanks a lot

Nand_gates you are correct..

Thank You all for your replies

Thanks,

Re: Digital Question

may be I'm blind, but I see the factor 2/3, not 3/2 ...
