摘要： Certain embodiments herein describe filtering signals or channels using a programmable bandwidth filter. Each channel may be filtered according to a different bandwidth such that noise may be removed from each channel without the need to increase the complexity of an anti-aliasing filter, for example. In one embodiment, the programmable filter may be a decimation filter that may be coupled to a delta sigma modulator, which may sample an analog channel according to a programmable sampling rate to generate a digital representation of the analog channel. In one embodiment, multiple analog channels may be multiplexed and subsequently sampled and filtered by the delta sigma modulator and decimation filter, respectively. According to various embodiments, the above processing may be performed by an application specific integrated circuit (ASIC), a microcontroller, or a computing device including one or more software programs and/or modules.
