Representing Data in the GUI
4 (Optional) In the Data Inform ation area, click More to expand the d ialog
box and enter the following settings:
Input Properties
• InterSample — This setting specifies the behavior of the input signals
between samples whe n you transform the resulting mode ls between
discrete-time and continuous-time representations.
–
zoh (zero-order hold) maintains a piecewise-co nstant input signal
between samples.
–
foh (first-order hold) maintains a piecewise-linear input signal
between samples.
–
bl (bandwidth-limited behavior) specifies that the continuous-time
input signal has zero power above the Nyquist frequency (equal to the
inverse of the sampling interval).
Note See the d2c and c2d reference pages for more information about
transforming between discrete-time and continuous-time models.
• Period —EnterInf to specify a nonperiodic input. For a periodic input,
type the pe r iod of the input signal in your experim en t.
Note If your data is periodic, always include a whole number of periods
for model estim ation.
Channel Names
• Input —Enterastringtospecifythenameofoneormoreinput
channels.
Tip Naming channels helps you to identify data in plots. For
multivariable input-output signals, you can specify the names of
individual Input and Output channels, separated by commas.
