subject: Embedded Digital Filtering [print this page] Introducing a powerful digital filtering engine into embedded applications extends the value developers can deliver to their customers, and it reduces system cost, complexity, and time-to-market. By making use of mixed-signal microcontrollers with programmable hardware signal processing resources, such as the PSoC3 device in these examples,it becomes possible to address the evolving requirements for complex signal filtering as they change during the design process. With them,developers can cost-effectively introduce a wide range of capabilities to enhance their products, from adding stereo enhancement' functions, to decimation filters for digital microphones, and even advanced control algorithms for industrial sensor conditioning and medical applications.
