An apparatus and method for efficient and concurrent sampling of a sensor signal to create multiple output signals each at different sampling rates is provided. The apparatus and method determine an aperiodic sampling rate or sampling schedule such that only samples representing samples at the different sampling rates are taken. The aperiodic samples are taken then de-interleaved to filter wanted samples for a particular application or user. As a result, the aperiodic samples is just a combination of all of the subsets to each application. Such aperiodic sampling reduces a total number of samples taken and, as a direct result, reduces the number of samples needing to be processed and stored and also reduced the power otherwise consumed to sample, process and store unused samples.
