pathsim.blocks.delay module

class pathsim.blocks.delay.Delay(tau=0.001)[source]

Delays the input signal by a time constant ‘tau’ in seconds using an adaptive rolling buffer.

Mathematically this block creates a time delay of the input signal like this:

\[\begin{split}y(t) = \begin{cases} x(t - \tau) & , t \geq \tau \\ 0 & , t < \tau \end{cases}\end{split}\]

Example

The block is initialized like this:

#5 time units delay
D = Delay(tau=5)

_buffer

internal interpolatable adaptive rolling buffer

reset()[source]: Reset the blocks inputs and outputs and also its internal solver, if the block has a solver instance.

Evaluation of the buffer at different times.

Parameters:: t (float) – evaluation time
Returns:: error – deviation to previous iteration for convergence control
Return type:: float

Sample input values and time of sampling and add them to the buffer.
