Latest Patents
Jung-Kuei Chang holds a patent for an "Asynchronous sample rate converter and method." This invention involves an asynchronous sample rate converter that interpolates and filters a digital audio input signal to produce a filtered, up-sampled first signal. A FIFO memory receives the first signal and stores samples at locations determined by a write address. The stored samples are then presented from locations determined by a read address. These samples are passed through an interpolation and resampling circuit to produce a continuous-time signal, which is re-sampled to create a signal that is up-sampled relative to a desired output. The output signal is then filtered and down-sampled. The invention also includes sample rate estimating circuitry that computes a difference signal, as well as address generation circuitry that generates the necessary read and write addresses. Additionally, a coefficient calculation circuit calculates filter coefficients for the interpolation and resampling circuit based on the difference signal. Jung-Kuei Chang has 1 patent to his name.
