       hi frnds

         

      i am using two counters for measuring freuency, one counter for 1 sec generation, another counter for counting pulses,

         

      after every one sec interrupt generate.

         

      now the problem is after 1 sec it does not give exact value

         

      eg.  if i take 10--->10,for 100-->98,for1000--->992,for 10000--->99960

         

      why it come like this,plz help?
