  • Reduced complexity adaptive filter
    Patent number: 7461113
    Abstract: A FIR filter for use in an adaptive multi-channel filtering system, includes a first memory for storing data, and a second memory for storing filter coefficients. The second memory stores only non-zero valued coefficients or coefficients that are above a predetermined magnitude threshold such that the overall number of coefficients processed is significantly reduced.
    Type: Grant

  • Clock synchronization over a packet network using SRTS without a common network clock
    Patent number: 7295559
    Abstract: A method for recovering a service clock through a packet network for the provision of isochronous services uses a two-layer arrangement wherein stable oscillators are provided at the transmitting and receiving nodes. ACR is used to tune the local oscillators over a long period of time. SRTS is used to transfer the service clock except the timestamp information is based on the local oscillators at the transmitting and receiving nodes instead of the common network clock.

  • Digital microphone
    Publication number: 20030235315
    Abstract: A digital microphone has a transducer for generating an analog signal representing an acoustic signal, and a single bit sigma-delta modulator analog-to-digital converter of order greater than one for generating a digital output signal from said analog signal in the form of a sigma-delta modulated bit stream at an oversampled rate. The digital microphone avoids the need to include digital decimation and filtering circuits within the microphone housing and thus lends itself better to integration technologies.
