   *Preamplifier - the output signal from the heartbeat measurement setup is decoupled through the series capacitor and amplified using a negative feedback resistor(R4).
   *Low-Pass Filter - RC filter that cuts the high frequencies (noise).
-  *[[university:courses:electronics:electronics-lab-1|Voltage Follower]] - buffers the output of the low-pass filter and reproduces its voltage with a low impedance output;
