AB  - Better accurate stethoscope measurements have been needed to diagnose heart 
      problems earlier, monitor patients, and provide initial clinical data for 
      physicians. This study aims to evaluate an electronic stethoscope for automatic 
      identification of heart rate by monitoring Beats Per Minute (BPM) in real-time. 
      In this work, a new design with a low cost electronic stethoscope is designed and 
      implemented as a simple circuit for a replacement with conventional stethoscopes. 
      This presented a low cost stethoscopes consisting of a preamplifier, low-pass 
      filter, high-pass filter, microcontroller and Bluetooth. This simulation and 
      experimental study was carried out for electronic circuit design testing. The 
      condenser microphone transmited the signal into the signal conditioning circuit, 
      and amplified it from 10 to 30 times. The low- and high- pass filter circuit was 
      with cutoffs of 180 Hz and 50 Hz, respectively. The result shows that the 
      fourth-order Butterworth filter was the best filter, with a gain of 0.707 Volt, 
      -3.01 dB, and 0.782 Volt, -2.137 dB, respectively. The real-time measurements 
      using the system are not significantly different from the manual measurements, 
      with around 2-5%, with a delay of 1.7 to 2 seconds. The results indicated that an 
      electronic stethoscope system could provide suitable information for BPM value 
      and could display heart sound signals.
