analog input time period measurement using DAQmx

Hi

I am new to labview, i am stuck in a task .

My task is to measure edge to edge  time periods of 10 pulses which will be analog input e.g initially 3.3 v is there then due to some block in sensor it is dropped to zero .& again if that blocking we took out it again come to 3.3v , so ineed timing of two high edges happened for 10 pulses.  .

and if it is with in range then add  to a variable else other variable .

Can anybody help me in this to create Block Diagram of the same

I need to capture time period for the following Pic .

thanks & regards
