| integer(kind=int32), | public, | parameter | :: | SPCTRM_H1_ESTIMATOR | = | 50002 |
A flag for requesting an H1 transfer function estimator. An H1 estimator is best used when noise is uncorrelated with the input, and results in a transfer function estimate of the form . |
| integer(kind=int32), | public, | parameter | :: | SPCTRM_H2_ESTIMATOR | = | 50003 |
A flag for requesting an H2 transfer function estimator. An H2 estimator is best used when noise is uncorrelated with the output, and results in a transfer function estimate of the form . |
Estimates the transfer function matrix for a multiple-input/ multiple-output (MIMO) system.

|---|---|---|---|---|---|---|
| class(window), | intent(in) | :: | win |
The window object. |
||
| real(kind=real64), | intent(in) | :: | x(:,:) |
An N-by-NIN array containing the input signals. |
||
| real(kind=real64), | intent(in) | :: | y(:,:) |
An N-by-NOUT array containing the output signals. |
||
| integer(kind=int32), | intent(in), | optional | :: | etype |
An optional input that, if supplied, denotes the estimator to use. Supported values are the same as for SISO transfer estimates. |
|
| integer(kind=int32), | intent(in), | optional | :: | nfft |
An optional input that can be used to force the length of each individual DFT operation by padding any remaining space with zeros. |
Returns the complex-valued transfer function estimate matrix.
Estimates the transfer function for a single-input/single-output (SISO) system.

|---|---|---|---|---|---|---|
| class(window), | intent(in) | :: | win |
The window object. |
||
| real(kind=real64), | intent(in) | :: | x(:) |
An N-element array containing the input signal. |
||
| real(kind=real64), | intent(in) | :: | y(:) |
An N-element array containing the output signal. |
||
| integer(kind=int32), | intent(in), | optional | :: | etype |
An optional input that, if supplied, denotes the estimator to use. If no value is specified, an H1 estimator is used. The following options are supported. |
|
| integer(kind=int32), | intent(in), | optional | :: | nfft |
An optional input that can be used to force the length of each individual DFT operation by padding any remaining space with zeros. If not supplied, the window size is used to determine the size of the DFT. |
Returns the complex-valued transfer function estimate.
