A performance evaluation method suitable for characterizing wide types of analog filters

摘要

A method to evaluate the performance of a wide type of analog filters is proposed. This method requires only a Microcontroller Unit (MCU), low-cost peripheral components, circuitry, and a mobile device, so it can be set up readily with an easily available development platform. This eliminates the cost of acquiring the expensive instruments that are usually used for such testing. Moreover, this performance evaluation platform can be used as a communication interface and bridge to an Internet of Things (IoT) system. The feasibility and extended scope of application of this platform represent a significant advance in the ability to conduct such testing. The measurements obtained by using the proposed method to evaluate analog filters show good agreement with the desired functionalities.
