Title:
ASYNCHRONOUS SAMPLE RATE CONVERTER
Document Type and Number:
Japanese Patent JP2006197599
Kind Code:
A
Abstract:
To provide a high-performance ASRC and a corresponding method for converting a sample rate from a first value to a second value, and to use the ASRC and the method for an oversampling input signal, a very large sampling factor of the converter, and a very small sampling factor.
In an asynchronous sample rate converter (1) including an n-tap polyphase filter ((n) is an integer) (2) and a computational entity (5, 9) for computing a filter coefficient, the computational entity is matched, and a Parzen window is used, or a secondary window is used to compute the filter coefficient.
