Application: Methods and systems for equalisation (Patent ID: US20240204741A1)
The patent filed by Cirrus Logic Inc. describes a method for equalizing a signal derived from an input device by applying an order-statistic filter in the frequency domain to generate a statistically filtered signal, which is then used to equalize the received signal. The equalization process involves setting an equalization target based on the statistically filtered signal and removing or suppressing components of the signal based on identified frequency bins.
Additionally, the method includes steps such as smoothing the statistically filtered signal using filters like moving average or Savitsky-Golay filter, applying weights to frequency bins of the discrete Fourier transform, and inverting smoothed median values. The patent also covers the implementation of the method using a trained neural network and provides for systems and electronic devices incorporating this equalization technique, such as smartphones, tablets, laptops, and home entertainment systems. Overall, the patent outlines a comprehensive method for signal equalization that can be applied to various input devices and electronic systems.
