In this paper, we have present the design and development of a three input Electrocardiogram (ECG) amplifier system. The system takes the physical pulse input using sticking electrodes stuck to the arms and right leg of the patient under observation. The model encompasses of instrumentation amplifier, which are used for signal conditioning of the pulse input from the patient’s body and displayed on CRO as the ECG waveform. This circuit is capable of achieving, amplifying the low amplitude and desired ECG signals. The system has been designed at 33 Hz to reject the power line frequency of 50 Hz, so as to protect the circuit from the major noise interference which is the power line frequency.
