DiscretePrimitives.UnitDelay

UnitDelay(; name, ic = 0.0)

A unit delay component that delays the input signal by one sample period.

Arguments

  • name: Component name
  • ic: Initial condition for the delay (default: 0.0)

Variables

  • u(t): Input signal
  • y(t): Output signal delayed by one sample

Description

Implements: y[k] = u[k-1], the fundamental discrete-time delay element.

Usage

PrimitiveComponents.DiscretePrimitives.UnitDelay(ic)

Parameters:

NameDescriptionUnitsDefault value
ic–

Connectors

  • u - This connector represents a real signal as an input to a component (RealInput)
  • y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} y\left( t \right) &= Shift(t, -1)\left( u\left( t \right) \right) \\ \frac{\mathrm{d} \mathtt{dummy.l}\left( t \right)}{\mathrm{d}t} &= 0 \end{align} \]
