Abstract:
1. A data processor for processing position-related input data from a rotational machine whose angular speed is variable and providing output data at an output data rate, the data processor comprising: an oversampling clock; an over-sampler coupled to the oversampling clock to over-sample said input data at an over-sampling rate greater than said output data rate based upon an output of the oversampling clock; a down-sampler for extracting samples of over-sampled data from said over-sampler at said output data rate so as to provide said output data; and an angular timing signal source for producing an angular timing signal related to an angular position of the machine, wherein said down-sampler is connected to said angular timing signal source for selecting said samples of over-sampled data to extract based on said angular position.
