Continuous- and Discrete-Time Conversions

Change model sample time

System Identification Toolbox™ offers several discretization and interpolation methods for converting identified dynamic system models between continuous time and discrete time and for resampling discrete-time models. Some methods tend to provide a better frequency-domain match between the original and converted systems, while others provide a better match in the time domain.
