8. From Wikipedia, the free encyclopedia: Heart rate is the speed of the heartbeat measured by the number of contractions of the heart perminute (bprn), Design a microprocessor based portable heart rate monitor to display instantaneous (beats per minute upscaled from the last1.875 second) heart rate every 1.875 second (1875 ms) by updating its display. You may assume that an interrupt generating source sendsperiodic request signals every 125 ms to be used as an interrupt driven timer. Audible heartbeat signal acquired by a microphone from astethoscope is amplified, sampled at 100 Hz and digitized by an 8-bit AID converter before reading in programmed I/O mode. AID convertersupplies End Of Conversion (EOC)signal to indicate that a converted sample is ready to be read. A heart beat pulse value above half of the fullscale of the AID converter (256/2) is assumed to be a contraction of the heart. You should state other assumptions you have to make in orderto design portable heart rate monitor. Hints: (1) Heart rate is often measured by counting beats for 15 seconds and multiplying the number ofbeats by 4. (2) 60 s = 32 x 1.875 sand 1.875 s = 15 x 125 ms. /I Vikipedi, bzgOr ansiklopedi'den: Kalp atirn hrz: (nabiz), dakikada kalbin kasilmasayrsi ile olculen hrzrdtr.
