Title: Holger Ernst: Patents in Video Signal Modulation and Integrated-Circuit Testing.
Introduction
Holger Ernst is an inventor associated with Hamburg, Germany, and U.S. Philips Corporation. His patent work addresses frequency modulation in color-video systems and methods for testing analog integrated circuits. The supplied information lists 2 patents.
Latest Patents
**Frequency Modulator Comprising an Adjusting Circuit.** This invention concerns a frequency modulator that processes the luminance signal of a color-video signal while chrominance information is carried on a modulated carrier. A capacitor adjusts the modulator’s voltage-to-frequency characteristic according to the relationship between the output signal’s period and the chrominance carrier’s quiescent period. Its charging and discharging behavior helps maintain the desired nominal frequency during synchronization pulses.
**Integrated Circuit for Independently Testing Individual Analog Internal Functional Blocks.** This invention proposes a way to test separate functional blocks within an analog integrated circuit, despite the limited number of external terminals. Switches connect selected block inputs and outputs to external terminals, while storage stages control the switches. A single test input, together with comparators and reference-voltage ranges, can convey clocked data that selects the desired test configuration.
Career Highlights
Ernst’s listed patents demonstrate work on both signal-processing circuitry and integrated-circuit test design. The video-modulation patent focuses on stabilizing frequency behavior, while the testing patent addresses access to internal circuit blocks for independent evaluation.
Collaborations
The supplied information identifies U.S. Philips Corporation as the company associated with Ernst and names Holger Moll as a coworker. It does not specify further details about their collaboration.
Conclusion
Holger Ernst’s two listed patents reflect contributions to color-video frequency modulation and practical testing of analog integrated circuits.
