Constructor & Destructor Documentation

wdfUnterminatedInd()

wdfUnterminatedInd::wdfUnterminatedInd	(	double	L,
		double	T
	)

Unadapted inductor model class.

Creates an unadapted inductor with capacitance L.

Parameters

L	physical inductance of the component in Henry
T	sample period T = 1/fs in seconds

Member Function Documentation

calculateDownB()

void wdfUnterminatedInd::calculateDownB ( vec *  ascendingWaves, vec *  descendingWaves, size_t *  portIndex  )

virtual

Calculates the reflection of the incoming, ascending wave.

This is composed of the recent ascending wave component and former components on this port.

Parameters

*ascendingWaves	Pointer to a vector of ascending waves
*descendingWaves	Pointer to a vector to store descending waves
*portIndex	Pointer to a counter with the port index to use in the vectors of ascending and descending waves. Needs to be incremented by numPorts in the node's implementation.

Implements wdfRootNode.

getNumPorts()

int wdfRootNode::getNumPorts ( )

inherited

Return the number of ports of that root node.

Returns

the value of the numPorts member.

getType()

std::string wdfUnterminatedInd::getType ( ) const

virtual

Returns a String describing the type of this root node.

Returns

a String describing the type of this leaf as "L (unadapted)"

Implements wdfRootNode.

setPortResistance()

void wdfUnterminatedInd::setPortResistance ( double  Rp )

virtual

Sets the nodes port resistance according to the port it is connected to.

TODO: In the case of the unadapted inductor, it also pre-calculates the reflection coefficient reflectionCoeff, which depends on the port resistance too.

Parameters

Rp	port resistance in Ohm

Reimplemented from wdfRootNode.

L

double wdfUnterminatedInd::L

Inductance in Henry

numPorts

size_t wdfRootNode::numPorts

protectedinherited

The number of ports on a root node element.

prevA

double wdfUnterminatedInd::prevA

protected

Place to store the previous incident wave component.

prevB

double wdfUnterminatedInd::prevB

protected

Place to store the previous reflected wave component.

reflectionCoeff
