Problems solved by technology

This can be disadvantageous when only one coefficient or a subset of coefficients is of interest, as the butterfly method spends time and resources determining the less important coefficients using the same resolution as the important ones

Embodiment Construction

[0073] The invention will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. Like numbers refer to like elements throughout the description.

[0074] As mentioned above, data processing systems have been developed for determining the coefficients of a function representing a signal. However, because many of these systems are complex and the coefficients are not calculated until all samples of the signal have been received, these systems do not provide immediate analysis of the signal. Furthermore, because these conventional systems are complex, it is not easy to provide individual coefficients for observation and tracking. Furthermore, these systems do not allow changing the resolution of individual coefficients or selected subsets of coefficients.

[0075] In another aspect, the present invention provides apparatus, methods and computer program products capable of reducing latency in de...

Abstract

The invention provides a data processing equipment for confirming the coefficient of the function, which comprises an input end of a plurality of sample values for receiving the input signal and a coefficient generator for generating the function coefficient. Wherein, the coefficient generator comprises a first equipment communicating with the input end for generating the signal representing the contribution of the function coefficient to be calculated for the sample value for the coefficient generator receiving the final sample, a second equipment communicating with the first equipment for generating the function factor based on the sample member and the coefficient member received from the second equipment. Wherein for the given sample and the coefficient member, the coefficient generator is installed that the second equipment transmits the sample and the function factor related to the coefficient member to the first equipment, the first equipment multiples the sample value by corresponding function factor to confirm the contribution of the sample value to the coefficient for the coefficient generator receiving the final sample, thereby minimizing the waiting time for confirming the coefficient of the function.

Description

[0001] This application was filed by Walter E. Pelton on April 28, 2000, the application number is 00808154.9, and the title of the invention is the case of "equipment, method and computer program product for determining function coefficients in reduced waiting time" divisional application. technical field [0002] The present invention generally relates to the determination of the coefficients of a function. More specifically, the apparatus, method and computer program product of the present invention relate to determining coefficients of a function representing an input signal as each sample of the signal is received so as to reduce latency in determining the coefficients. Background technique [0003] Signal processing is an important function in many electronic systems. Specifically, in many electronic systems, data is transmitted in the form of signals. In addition, certain electronic systems analyze and monitor the operation of mechanical and chemical systems by obse...
