Latest Patents

One of his latest patents is a method for determining the signal strength at the input of a tuner. This invention relates to a method for accurately measuring the strength of a signal at the input of a tuner. The frequency-dependent amplification characteristic for the tuner is measured and stored in a memory assigned to the tuner. This allows for compensation of the frequency-dependent variation of the amplification during tuner operation, leading to a more precise deduction of input signal strength. Additionally, for tuners with automatic gain control (AGC), the frequency dependence of the AGC can also be recorded and stored, further improving the precision of input signal strength estimation.

Another significant patent is for a television signal receiver with a universal output for surface-acoustic wave filters of different types. This invention involves a television signal receiver that includes a radio-frequency tuner and at least one surface-acoustic wave filter. The RF tuner filters an RF television signal and converts it to an intermediate-frequency television signal, which is then coupled to the surface-acoustic wave filter. The design allows for flexibility in switching between different outputs and enhances the functionality of the television signal receiver.
