Title: Method and device for estimating accidental error in estimated value of transfer function
Inventor: ONO TAKAHIKO
IPC: G01H15/00
Filed: 1988-11-14
Abstract: PURPOSE:To estimate the value of an accidental error included in the estimated value of a calculated transfer function by obtaining the difference of average transfer functions based on the data of each odd and even number. CONSTITUTION:Each of input and output signals of a transmission system for signals to be estimated is segmented via a time window of a prescribed function form to obtain the discrete Fourier transformation data Xi(k) and Yi(k), where (k) means a discrete frequency with (i) showing a time window number respectively. Based on these transformation data, the mean value of N times (N: an even number) is obtained for the transmission function of the frequency (k). In this case, an average transmission function equation I of each N/2 times is calculated based on the data on each odd and even number of the time window. Then an error is obtained based on the difference of the values calculated from both equations I, where a mark (*) shows the complex conjugation. Thus it is possible to estimate an accidental error included in the estimated value of the transmission function obtained from the average of a certain number of times.

A 1st means multiplies gradation data L and subtracts (N-1)×L/2 from the result, where N is the number of gradations and L is the number of scanning electrodes selected at the same time. A 2nd means performs matrix operation for the data obtained by the 1st means with an orthogonal coefficient represented as 1 and -1 of a scanning-side signal, and perform L×(N-1)×L/2 addition and division by L as to the data obtained through the operation, where N is the number of gradations and L is the number of scanning electrodes selected at the same time. Then the gradation data ate converted by this means and the data is only driven by a segment driver to enable multi-line driving.
