Electrocardiography (ECG) is the process of recording action potentials of the heart over a period of time using electrodes placed on the skin. Electrodes sense small electrical potentials on the skin and the signal is amplified, conditioned, and displayed to give a representation of the heart’s electrical activity. The purpose of this project is to gain experience building and designing analog circuits to process the ECG signal. Student is required to write an individual report: includes: inro, summarized methods, data, results, discussion, and conclusion.

  1. Complete the hardware design of Labs 1-4 of the BSL PRO Signal Processing Breadboard Labs. Complete recordings for each Lab and review the analysis and data report sections.
  2. Turn in Data Reports for Lab 3 and Lab 5 (do not build the notch filter). For Lab 5, conduct Recording 2 – ECG and exclude data report questions 1b, 2, and 3. Please include graphs for questions 4 – 6.

Note: protocol of labs is attached some data collected pictures. 9 more data pictures can be uploaded privately, since I can't upload more than 5 files.

Electrocardiography (ECG) is the way toward recording potentials of the heart
over some stretch of time applying the cathodes set on the skin. Anodes sense little
electrical potentials on the skin and the signal is increased, adapted, and shown to give a
portrayal of the heart's electrical movement. The objective of this experiment is to pick
up experience planning and designing simple circuits to process the ECG signal. In fact,
the heart can pump blood by means of the cardiovascular directing system where the
sinoatrial node creates an electrical impulse, otherwise called an action potential, which
starts withdrawal by applying particle channels on the cell membrane of cardiovascular
cells (Julian et. al., 2005). The cells, cardiomyocytes, likewise have a trans-membrane
potential, which is the voltage contrast between within and outside of a cell. The
electrophysiology of ECG signal can be measured utilizing a patch clamp procedure. This
strategy includes a high-determination recording of current in extracted membranes and
additionally cell-attached patches, which yields conductance and dynamic conduct of
ionic channels. A cell membrane must be electrically confined from an outside
arrangement and the current flowing into the patch must be recorded. To do this, a firecleaned glass pipette...
