signalproc.filtering.freqdomain.HetdyneF

All Implemented Interfaces:

ProcessDoublesInterface

public class HetdyneF
extends Unit
implements ProcessDoublesInterface

A HetdyneF_old unit to take an input ComplexSpectrum and output two ComplexSpectrum's that represent the FTs of the two quadruature components of the heterodyne of the time-series that led to the input ComplexSpectrum. (These are the results of heterodyning with cosine and sine at the heterodyne frequency.) The user can choose the heterodyne frequency and bandwidth. The user can select that the output spectra should have their Nyquist frequency reduced so that when they are inverted to the time-domain they are sampled at the rate given by the heterodyne bandwidth rather than the original sampling rate.

public HetdyneF()

Method Detail

process

public void process()
             throws java.lang.Exception

Description copied from class: Unit

The main unit algorithm. This method should be implemented with the appropriate algorihtm for the unit (if no algorithm is implemented deadlock occurs).

Specified by:

process in class Unit

Throws:

java.lang.Exception

init

public void init()

Called when the unit is created. Initialises the unit's properties and parameters.

Overrides:

init in class Unit

reset

public void reset()

Called when the unit is reset. Restores the unit's variables to values specified by the parameters.

Overrides:

reset in class Unit

dispose

public void dispose()

Called when the unit is disposed of.

Overrides:

dispose in class Unit

parameterUpdate

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

Called a parameters is updated (e.g. by the GUI)

Overrides:

parameterUpdate in class Unit

getRequireDoubleInputs

public boolean getRequireDoubleInputs()

Specified by:

getRequireDoubleInputs in interface ProcessDoublesInterface

Returns:

true if this unit requires its inputs to be in double precision format

getCanProcessDoubleArrays

public boolean getCanProcessDoubleArrays()

Specified by:

getCanProcessDoubleArrays in interface ProcessDoublesInterface

Returns:

true if this unit can deal with double precision input values

setRequireDoubleInputs

public void setRequireDoubleInputs(boolean state)

Description copied from interface: ProcessDoublesInterface

Unit Programmers should set this to true if this unit requires its inputs to be in double precision format

Specified by:

setRequireDoubleInputs in interface ProcessDoublesInterface

setCanProcessDoubleArrays

public void setCanProcessDoubleArrays(boolean state)

Description copied from interface: ProcessDoublesInterface

Unit Programmers should set this to true if this unit can process input data sets in double precision format

Specified by:

setCanProcessDoubleArrays in interface ProcessDoublesInterface

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:

an array of the input types for NewHetdyneF

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 NewHetdyneF
