As medical technologies advance, there is a greater need for remote monitoring of patient vital signs and the equipment that provides their care. This has led to an increase in high-frequency communication signals from systems such as Bluetooth and WiFl. These high-frequency signals can potentially interfere with sensitive medical equipment. One common approach to combating high-frequency noise in the power input to sensitive devices is to use something called a choke. Chokes come in multiple types, but one of the simplest is just an inductor. Consider an inductor that is placed in series with a power supply for a medical monitor. The inductor is designed to filter out high-frequency noise. An inductor with an inductance of 5. 5×10−3H is used to filter noise in a power line with a frequency of 150kHz.
