1. A method of generating data for a spectral Doppler strip in an ultrasound system comprising the steps of:
- providing Doppler data to an autoregressive model;
determining autoregressive parameters responsive to the Doppler data with said autoregressive model;
generating information responsive to said auto-regressive parameters; and
applying a window function to the information.

Abstract
A method and system for generating data for a spectral Doppler strip in an ultrasound system includes a beamformer that provides Doppler data to a signal processor. The signal processor applies an autoregressive model and determines autoregressive parameters responsive to the Doppler data. Information responsive to the autoregressive parameters is generated, and a window function is applied to the information. At least one spectrum responsive to the autoregressive parameter is estimated with a Fourier transform.
