How to switch from discrete to continuous filter?
You can switch between continuous and discrete implementations of the integrator using the Sample time parameter. To configure the filter for continuous time, set the Sample time property to 0. This representation is equivalent to the continuous transfer function:
How is a digital filter implemented in discrete time?
In discrete-time systems, the digital filter is often implemented by converting the transfer function to a linear constant-coefficient difference equation (LCCD) via the Z-transform. The discrete frequency-domain transfer function is written as the ratio of two polynomials.
How is the discrete representation equivalent to the transfer function?
The discrete representation is equivalent to the transfer function: K is the filter gain. T is the filter time constant. Ts is the filter sample time. From the discrete transfer function, the filter equations are defined using the forward Euler method: u is the filter input. x is the filter state.
What is the sample time and time constant for a low pass filter?
In the continuous case, the sample time and time constant must both be zero. Low-pass filter input signal. The block uses the input initial value to determine the state initial value. Low-pass filter output. Low-pass filter gain. Low-pass filter time constant.

How is the preceeding transfer function equivalent to continuous transfer?
This representation is equivalent to the continuous transfer function: K is the filter gain. T is the filter time constant. From the preceeding transfer function, the filter defining equations are: u is filter input. x is filter state. y is filter output. t is simulation time. u0 is the initial input to the block.
