A power generating system comprises a condenser and a deaerator apparatus. The classifier is autonomous in that it can perform three functions that define autonomic systems: automatically configure itself in an environment, optimize its performance using the environment and mechanisms for performance, and continually adapting to improve performance and heal itself in a changing environment. The present invention allows for the use of lower bit-resolution, lower power consumption, and less expensive filter ICs than conventional FIR filters implemented in a single IC.
