Latest Patents

Joseph Risley Perrin holds a patent for a test technique for set-top boxes. This patent describes a test system designed to identify missing or shorted parts within a tuner circuit. The system utilizes a signal generator to apply a harmonic-containing baseband time-varying RF test signal to the tuner circuit. The tuner circuit is tuned to a harmonic of the test signal, and a detector coupled to the baseband IF output detects the voltage generated in response to the applied RF test signal. A voltage measurement device measures the detected voltage to provide an indication of the gain. Significant changes in the gain can indicate missing parts or short circuits, making this invention crucial for ensuring the functionality of electronic devices.
