Title: Rolf P Anderson: Innovator in Signal Analysis Systems
Introduction
Rolf P Anderson is a notable inventor based in Portland, Oregon, recognized for his contributions to signal analysis technology. With a total of three patents to his name, Anderson has made significant advancements in the field, particularly in calibration methods and bandwidth extension for oscilloscopes.
Latest Patents
One of Anderson's latest patents is a "Signal analysis system and calibration method." This invention provides a method and apparatus designed to calibrate a signal path of a signal analysis system, effectively removing loading effects from measurements of a device under test. The system couples a signal under test from the device to a test probe, utilizing selectable impedance loads to characterize transfer parameters. An equalization filter is computed from these parameters to reduce signal error attributable to measurement loading.
Another significant patent is the "Method and apparatus for providing bandwidth extension and channel match for oscilloscopes." This invention selectively offers bandwidth extension and channel matching for acquired signals under test. It includes a signal acquisition device that generates a stream of acquired samples, with a digital filter that imparts a gain equalization function to the samples within a spectral region extending beyond the nominal passband.
