Project Overview

The project aims to create a functioning and accurate Heart Signal Analysis Circuit through software-based simulation, using Pspice, and find the BPM of patients from ECG data. Subsequent amplification, integration, multiplication, and filtering techniques are applied to obtain a digital signal from which the Pulse Rate is extracted. The heart Rate Monitor Circuit is a crucial component in biomedical instrumentation and health tracking systems.

Features

Amplification of weak bio-signals (heartbeat pulses)

Filtering of high-frequency noise (above 50 Hz)

Visualization of the processed signal

Simulation using PSpice or Proteus

Circuit Design Stages

Signal Acquisition: Simulated electrodes detect heartbeat signals.

Instrumentation Amplifier: Provides high common-mode rejection.

High-Pass Filter: Removes baseline wander (cutoff ~0.5 Hz).

Low-Pass Filter: Filters out high-frequency noise (cutoff ~50 Hz).

Real-Life Applications

HEALTHCARE INDUSTRY: Heart rate monitor circuits are crucial in medical equipment like ECG machines, helping doctors monitor and diagnose cardiovascular conditions more effectively.
FITNESS INDUSTRY: Portable heart rate monitors integrated into smartwatches or fitness bands allow athletes and fitness enthusiasts to optimize their workouts based on real-time heart rate data.
RESEARCH: In academic and R&D settings, heart rate monitor circuits can be used in studies examining human physiology, stress, and the effects of various interventions on cardiac health.
PERSONAL USE: DIY heart rate monitor kits and readily available devices enable individuals to track their heart rate for personal wellness, potentially alerting them to irregularities that may require medical attention.

Output Stage: Displays the cleaned signal on an oscilloscope.
