UNIVERSAL HARDWARE/SOFTWARE FEEDBACK CONTROL FOR HIGH-FREQUENCY SIGNALS |
摘要 |
<p>A method and apparatus for providing closed loop feedback control is presented. The method consists of a hybrid software and hardware solution to take advantage of the useful attributes of both. Analog signals output by the device are sampled at a rate sufficient to preserve all necessary high frequency information, and preprocessed at high speed in hardware. The outputs of the preprocessing stage are then operated on in software at much lower speeds. The method and apparatus allow for the complex real time processing of feedback signals in the digital domain, yet allow the cost efficiencies and programming flexibility of a standard micro-controller to be utilized.</p> |
