Constructor & Destructor Documentation

wdfTerminatedLeaf()

wdfTerminatedLeaf::wdfTerminatedLeaf

(

)

Base class for adapted leafs in WDF subtrees/branches.

This includes all linear one-port elements with one terminated upfacing port and non-implicit behaviour.

Member Function Documentation

adaptPorts()

double wdfTreeNode::adaptPorts ( double  T )

inherited

Recursively adapts all ports in the tree.

This recursion should be initiated from the base of the tree. It sets port resistances of all upfacing ports according to component values and/or adaptation rules and copies it onto connected downfacing ports in the parent.

Parameters

T	sample period as specified by setSamplerate()

Returns

a double type up-facing port resistance of that WDF element

calculateDownB()

virtual void wdfTreeNode::calculateDownB ( double  descendingWave )

pure virtualinherited

Virtual placeholder function that is meant to set the wave components in the downfacing ports.

This function processes the input wave correctly for the downfacing ports and sets them in the port objects.

Parameters

descendingWave

incoming wave component on the upfacing port

Implemented in wdfTerminatedResVSource, wdfTerminatedRes, wdfTerminatedInd, wdfTerminatedCap, wdfInverter, wdfTerminatedParallel, wdfTerminatedSeries, and wdfTerminatedRtype.

calculateScatterCoeffs()

void wdfTerminatedLeaf::calculateScatterCoeffs ( )

virtual

This variant of the base classes' calculateScatterCoeffs() function is an empty function to break the recursion that only applies to adapters and stops here at the leafs.

Implements wdfTreeNode.

calculateUpB()

virtual double wdfTreeNode::calculateUpB ( )

pure virtualinherited

Virtual placeholder function that is meant to return the upfacing wave component towards the root.

This function is called from pullWave() to calculate the wave that travels towards the base according to the element type.

Returns

the upward traveling wave of a node

Implemented in wdfTerminatedResVSource, wdfTerminatedRes, wdfTerminatedInd, wdfTerminatedCap, wdfInverter, wdfTerminatedParallel, wdfTerminatedSeries, and wdfTerminatedRtype.

calculateUpRes()

virtual double wdfTreeNode::calculateUpRes ( double  T )

pure virtualinherited

Virtual placeholder function that is meant to return the nodes' upfacing port resistance.

This function is called from adaptPorts(). It returns the upfacing port resistance of a tree node to fulfill adaptation according to the respective adaptation law of this node.

Parameters

T	sample period T = 1/fs as needed to adapt capacitors/inductors

Returns

a double type port resistance of that element in Ohms

Implemented in wdfTerminatedResVSource, wdfTerminatedRes, wdfTerminatedInd, wdfTerminatedCap, wdfInverter, wdfTerminatedParallel, wdfTerminatedSeries, and wdfTerminatedRtype.

createPorts()

void wdfTreeNode::createPorts ( )

inherited

Recursively creates WDF ports in the tree.

This recursion should be initiated from the base of the tree. It creates downfacing ports for all children and an upfacing port in each child while setting the correct pointers to the nodes that these ports are connected to.

getType()

virtual std::string wdfTreeNode::getType ( ) const

pure virtualinherited

Virtual placeholder function that is meant to return a String describing the type of this node.

Returns

a String describing the type of this root

Implemented in wdfTerminatedResVSource, wdfTerminatedRes, wdfTerminatedInd, wdfTerminatedCap, wdfInverter, wdfTerminatedParallel, wdfTerminatedSeries, and wdfTerminatedRtype.

pullWaveUp()

double wdfTreeNode::pullWaveUp ( )

virtualinherited

Recursively pulls the wave from the leafs towards the root.

This recursion should be initiated from the base of the tree. As all tree nodes are adapted, it basically just pulls up correctly scattered states of reactive elements and input values from adapted sources.

Returns

the upward traveling wave of a node

pushWaveDown()

void wdfTreeNode::pushWaveDown ( double  descendingWave )

virtualinherited

Recursively pushes the wave from the root towards the leafs.

This recursion should be initiated from the base of the tree. It pushes the respective wave component of a branch from the root to the leafs by scattering them correctly along the way.

Parameters

descendingWave

descending wave component that shall be scattered to the downfacing ports of the node or processed in a leaf accordingly

setParentInChildren()

void wdfTreeNode::setParentInChildren ( )

inherited

Recursively sets pointers to parent node in children.

This recursion should be initiated from the base of the tree. It sets a pointer to *this parent node in all connected children.
