Tag: Band Pass Filter

Abstract Over the years, many circuit designs were developed for detecting the electrical activity of theheart (ECG signal). The main aim was to reduce the noise and improving the efficiency and quality of thesignal obtained from the heart. In this paper a suggested design of a single channel ECG circuit isintroduced, it shows how to build the ECG circuit step by step, investigates the quality of the signalobtained after adding each stage of the circuit and offers a suggestions and ideas of the best circuit designand the best ICs that can be used to reduce the noises to get the best quality of ECG signal. This design iscomposed of the usual main parts which are instrumentation amplifier (IA), isolation circuit (iso-amp),band pass filter, and right leg circuit, in addition to a suggested first and second order band pass filter anda notch filter. The advantages of this design are its simplicity and high efficiency which represents in itsability to obtain a good quality signals with minimum noises, as it has many stages of filtration, in additionto its low cost which offers the opportunity to manufacture it in Jordan.
