Patent ID: 7342525

Claim:
A method of of converting input data samples provided at a first sample rate to an analog output signal, comprising the steps of: converting, by a Delta Sigma Modulator (DSM) in a Digital to Analog Converter (DAC), where internal states of the DSM are updated at a second sample rate unequal to the first sample rate, the input data samples to produce output data samples at the second sample rate; in response to a new input sample arriving at a time different from an update of the internal states of the DSM, modifying at least one internal state of the DSM to account for the time difference; and converting the output samples to an analog output signal, wherein the step of modifying comprises the step of modifying the at least one internal state in response to an amount of time elapsing between when an input data sample arrives and the update of the internal states of the DSM.
