TRestRawSignalAddNoiseProcess Class Reference

Detailed Description

A process to add/emulate electronic noise into a TRestRawSignalEvent.

TRestRawSignalAddNoiseProcess is a process that allows to add a random gaussian noise to the input TRestRawSignalEvent.

The process makes use of TRestRawSignal::GetWhiteNoiseSignal which simply adds a random gaussian value centered on zero and with a sigma given by the parameter noiseLevel.

The process can be defined as follows:

<parameter name="noiseLevel" value="10" />
A process to add/emulate electronic noise into a TRestRawSignalEvent.

or

<TRestRawSignalAddNoiseProcess name="noise" noiseLevel="10" />

Constructor & Destructor Documentation

◆ TRestRawSignalAddNoiseProcess()

TRestRawSignalAddNoiseProcess::TRestRawSignalAddNoiseProcess ( const char *  configFilename)

Constructor loading data from a config file.

If no configuration path is defined using TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters
configFilenameA const char* giving the path to an RML file.

Definition at line 97 of file TRestRawSignalAddNoiseProcess.cxx.

◆ LoadConfig()

void TRestRawSignalAddNoiseProcess::LoadConfig ( const std::string &  configFilename,
const std::string &  name = "" 
)

Function to load the configuration from an external configuration file.

If no configuration path is defined in TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

Parameters
configFilenameA const char* giving the path to an RML file.
nameThe name of the specific metadata. It will be used to find the corresponding TRestGeant4AnalysisProcess section inside the RML.
