A system and method for filtering an analog signal with a finite impulse response filter that does not require analog delay elements are disclosed. The inlet is adapted to receive a fluid therethrough, and the first and the second outlets are adapted to simultaneously emit a fluid therethrough. In one embodiment the apparatus is incorporated into a backpack. The plurality of decoded uncommon memory address portions is used to determine whether to enable the modified SA. Additionally, cache location avoid storage is provided having at least one record, with each record being used to store a cache line identifier identifying a specific cache line. Also disclosed are systems for implementing the processes.
