First, the insertion loss a general filter is defined, and then the impact of the source and load impedance on the insertion loss is investigated. Simulations and measurements focus on the CL and LC filters. In Part II (to appear in the next issue) the performance of the Pi and T filters is evaluated and compared to that of the CL and LC filters.

EMI is a serious concern for devices that are externally powered (ones that have a plug) or require signal wires that need to extend outside the device (signal wires that might attach to sensors or input/output devices). The wires that connect to power sources, or I/O points, can act as antennas that will allow EMI to be received (coupled onto them) and enter the device.
