Process ( amplify ) the sensor output to get a reasonable amplitude pulse. Have a Schimdt trigger to convert to sharp edged pulses. feed these pulses to bistable multivibrator Measure the period of the pulse from BMV(this is the time between two heart beats). Calculate the frequency and multiply by 60 to get the pulse rate.. abhishek |
