Latest Patents

Guo-Hau Gau's latest patents include innovative technologies that improve broadcast reception. One of his patents is titled "Broadcast receiver and method for regulating the same." This invention features a broadcast receiver that includes a tuner circuit and a demodulator circuit. The tuner circuit is designed to tune a radio frequency (RF) signal, outputting an intermediate frequency (IF) signal. The demodulator circuit then demodulates the IF signal and outputs a command signal based on its quality, allowing for adjustments to the take over point (TOP) value preset in the tuner circuit. This method enhances the overall performance of the broadcast receiver.

Another significant patent is the "Carrier recovery apparatus and method thereof." This apparatus includes a pilot strength detector, a first lock loop, a second lock loop, and a controller. The pilot strength detector assesses whether the pilot strength of an input signal exceeds a threshold value, generating a control signal. The first lock loop performs the initial carrier recovery, while the second lock loop executes a secondary recovery. The controller intelligently selects which lock loop to utilize based on the control signal, optimizing the recovery process.
