Abstract

A switching converter includes a power stage that receives an input voltage for converting it into an output voltage and provides a load current to a load operably coupled to the power stage. The power stage includes a switch providing a switching voltage and a controller comprising an integrator and a comparator with hysteresis and configured to regulate the output voltage to a level proportional to a reference voltage by controlling the switching voltage.

Abstract

The present invention constitutes a method, processes, and apparatus for measurement and analysis of variables of different type and origin. In particular, the invention presents a method and apparatus for real-time signal conditioning and analysis in the presense of impulsive, or sparse interferences. The present invention overcomes limitations of the prior art by providing a novel method for identifying and discriminating between, in real time, the conditions of the signal with and without impulsive disturbances. This method can be implemented without substantial changes in the signal processing chain of a communication or data acquisition system. The present invention also overcomes the shortcomings of the prior art through the introduction of the novel SPART filters, which can replace the corresponding analog linear filters in the signal chain of a device. SPART filters have the ability to sense and discriminate between, in real time, the conditions of the signal with and without impulsive disturbances, and temporarily adjust their behavior in a manner which reduces the power of these disturbances.
