The main purpose of biomedical devices disrupts the health of human beings, negative quality of life The determination of the factors affecting, that is, the diagnosis of the disease. The first stage of diagnosis After listening to complaints and examining the symptoms, the complaint with reliable methods Evidence of the subject is collected, ie a number of examinations should be done. Today, traditional listening, hand polling, observation methods, as well as observation Advanced modern devices that provide decision support to physicians are used in diagnosis. These devices are various physiological events, electrical events that occur in the sick body, Normal events of physicians by detecting their deformities and biological changes in tissues and comparison with tissues and help them decide on the shape of treatment. In the perception of these events that occur in the human body Many electronic devices are used in the processing of the data. Extremely Small electrical signs, ultrases waves that rotate from body tissues, reactions to the magnetic field in tissues or radiation passing through body tissues By various circuits after being detected by the sensitive sensor of medical devices processed. However, the purification of these signs from many disruptive effects before the processing is the process The circuits must be upgraded or reshaped at the level they can process. At this stage, the most important part of the electronic systems from the amplifiers utilized. The amplifiers are not only for the purpose of strengthening weak signals, but Filtering distorting signals at the time, making mathematical operations, wave It can also be used for shaping, regulation. Processing Occupants Due to the many positive features they have, in the processing of biopotential signs are commonly used circuit elements. In this course, it is widely preferred in the design of biopotential amplifiers. Processing amplifiers and various application circuits will be examined. Processive Occupants are good Somehow understanding will provide an important advantage for anyone interested in electronics. The application areas of the operational amplifiers are limited to the issues discussed in this course. It is not widely available in almost every field.
