Use filt to create discrete-time transfer function models in digital signal processing (DSP) form for use with Control System Toolbox™ linear analysis and control design tools. To apply a filter to vector dat
This MATLAB function converts the discrete-time filter System object to numerator and denominator coefficient vectors of the equivalent transfer function.
Create the discrete-time transfer function with a sample time of 0.1 seconds. Hd = tf([1 1],[1 1 1],0.1); Specify the discretization method as bilinear (Tustin) approximation and the prewarp frequency as 20 rad/seconds. opts = d2cOptions('Method','tustin','PrewarpFrequency',20); ...

[sysd,G] = c2d(___), where sysc is a state-space model, returns a matrix, G that maps the continuous initial conditions x0 and u0 of the state-space model to the discrete-time initial state vector x[0].Examples collapse all Discretize a Transfer Function This example uses: Control ...
Create discrete-timezpk,ss, andfrdmodels in a similar way to discrete-time transfer functions, by appending a sample time to the input arguments. For examples, see the reference pages for those commands. See Also tf|zpk|ss|frd Topics ...

This MATLAB function converts a the discrete-time dynamic system model sysd to a continuous-time model using zero-order hold on the inputs.
This MATLAB function computes the linear state-space model with sample time Ts of the discrete-time system represented in the model mdl by linearizing each block in a model one by one.
If the Z-transform of a signal or the transfer function of a system is defined on the unit circle then the discrete-time Fourier transform (DTFT) of the signal or the frequency response of the system are obtained. Duality in time and in frequency is used otherwise to obtain DTFTs of ...
