pls gimme the solution(asked in interview to me)

[kameshvedula]

this question was asked to me in an interview...

there are two flipflops....one flip flop(FF) was havng a clk of 10MHz and the other 18MHz...the o/p of 10MHZ FF was fed directly to I/P of 18MHz FF.now wht are the problems in this circuit(if any) and what are the remedies for them,,,,,take the FF as T-FF

 

[thedesolatesoul]

actually i think that the 18MHz flip flop should be able to handle the 10MHz input with no problems at all.

Is this what you ment?

If yes, than there is posibility of getting glitches. Depends of your input, and of what you want at the output...

 

[cydi]

Yes, since the sampling times are not really compatible, glitches can occur at some points. Depends on the function. If a divider is what is meant, they may not be severe

 

[afzal ahmed1]

yes the circuit may not function properly that way
