Document Type and Number:
Japanese Patent JP2532204
Kind Code:
B2
Abstract:
A transfer function analyzer measures the real and imaginary parts of the Fourier transform of a stimulus signal applied to a device and of a resulting response signal. The integration which is performed as part of the Fourier transformation is performed as a summation of a central sector of discrete data points within the period of integration plus the products of the coefficients of weighting polynomials multiplied by preceding and succeeding sectors of data points beyond the central sector. An accurate integration is obtained whether or not the period of integration begins or ends upon discrete data points.
