Themen

Discretizing and Resampling Models
This example shows how to use the commands for continuous/discrete, discrete/continuous, and discrete/discrete conversions.
Discretize a Compensator
This example shows how to convert a compensator from continuous to discrete time using several discretization methods, to identify a method that yields a good match in the frequency domain.
Discretizing a Notch Filter
This example shows the comparison of several techniques for discretizing a notch filter.
Improve Accuracy of Discretized System with Time Delay
This example shows how to improve the frequency-domain accuracy of a system with a time delay that is a fractional multiple of the sample time.
Convert Discrete-Time System to Continuous Time
This example shows how to convert a discrete-time system to continuous time using d2c, and compare the results using two different interpolation methods.
Continuous-Discrete Conversion Methods
Choose discretization and interpolation methods for converting between continuous and discrete models.
Upsample Discrete-Time System
This example shows how to upsample a system using both the d2d and upsample commands and compare the results of both to the original system.
Choosing a Resampling Command
Use resampling commands to change the sample time of a discrete-time system.
