Design of advanced digital heartbeat monitor using basic electronic components

This paper illustrates the design of an efficient, stable, accurate and cheap digital heartbeat monitor which accepts the mechanical heartbeat pulses as input, converts them into the electrical form, amplifies them and provides the necessary output on a 7 segment display following a basic logic algorithm. The reading which is obtained in the seven segments is made error free by using suitable cascading flip flop mechanism. An accurate result is thus obtained.
