Doctors record heart sound signals from patients in hospitals in an environment in which many background noises occur. This will be from people or from essential medical equipment and devices operational in the environment. In this assignment you are to prepare a filter that removes noise produced by electronic medical equipment. It is known  that the equipment in question emits a tone at 2000 Hz. Design a filter that can remove this component, whilst having the minimum impact on the heart sound signal recorded. You are given with a test sound signal.
