Discrete derivative

		`\| Vector \| C \|`
`в палитре`	`на схеме`	`\| Vector \| C \|`

The block implements the numerical determination of the derivative according to the formula:

where x_i( t[k] ), x_i(t[k-1] ) are the values of the i-th element of the input signal to the block at the last and at the next to last sampling moments t[k], t[k-1]; y_i(t) is the i-th element of the output signal from the block at the current moment of the model time.

Входные порты

input – the port for the input signal of the block.

Выходные порты

output – the output port of the block.

Свойства

Sampling period – sampling period of T block calculation.
Initial conditions – vector of initial values y_i of the block output.

Параметры

none

Прим.:

By default, the block implements scalar input signal processing.
Coefficients a_i, b_j are introduced according to increasing powers z. For the proper operation of this unit, it is necessary to set the maximum integration step no more than 0.5·T. When integrating with a constant step, it is recommended to set the step such that the quantization period is a multiple of the integration step T = k·h, where k, h is an integer and the integration step.
