signalproc.filtering.timedomain.LPAverage

public class LPAverage
extends Unit

A LPAverage unit to implement a convolution in the time domain, working forward from the first data element, ie for input data {x(k)}, the filter coefficients {a(k)} lead to output {y{k}):<\p>

y(n) = a(0)x(n) + a(1)x(n+1) + a(2)x(n+2) + ... <\p>

The user gives an arbitrary number of coefficients and the unit applies them to the input data.

Method Detail

process

public void process()
             throws java.lang.Exception

********************************************* ** USER CODE of LPAverage goes here *** *********************************************

Specified by:

process in class Unit

Throws:

java.lang.Exception

init

public void init()

Initialses information specific to LPAverage.

Overrides:

init in class Unit

reset

public void reset()

Reset's LPAverage

Overrides:

reset in class Unit

parameterUpdate

public void parameterUpdate(java.lang.String name,
                   java.lang.Object value)

Used to set each of LPAverage's parameters.

Overrides:

parameterUpdate in class Unit

getInputTypes

public java.lang.String[] getInputTypes()

Description copied from class: Unit

This method should return an array of the data types accepted by nodes not specified in getNodeInputTypes (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getInputTypes in class Unit

Returns:

a string containing the names of the types allowed to be input to LPAverage, each separated by a white space.

getOutputTypes

public java.lang.String[] getOutputTypes()

Description copied from class: Unit

This method should return an array of the data types output by nodes not specified in getNodeOutputTypes() (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getOutputTypes in class Unit

Returns:

an array of the output types for this unit

getPopUpDescription

public java.lang.String getPopUpDescription()

This returns a brief! description of what the unit does. The text here is shown in a pop up window when the user puts the mouse over the unit icon for more than a second.

Overrides:

getPopUpDescription in class Unit

getHelpFile

public java.lang.String getHelpFile()
