Description
This project aims to design portable ECG signal amplifier and filter circuit.
Electric circuit combines In-Amp circuit with variable gain control and Twin-T Notch Filter circuit with variable Q value control in order to have more freedom over bandwidth filtering.
PCB is designed to satisfy production standards at Royal Holloway, University of London, mounting holes are in place to ensure fit for the portable case(currently in desing)
Future plans include screen for visualising the ECG waveform.
