Detailed Description

ahdc signal simulation

This class simulates the waveform of the ahdc signal and provide algorithms to extract relevant informations from this signal.

As it is written, it can only be used on the ifarm :-(

Member Function Documentation

Digitize()

void ahdcSignal::Digitize

(

)

Digitize the simulated signal.

This method perfoms several steps

• step 1 : it produces samples from the simulated signal (using samplingTime)
• step 2 : it converts keV/ns in ADC units (using electronYield)
• step 3 : it adds noise

Returns

Fill the attributs Dgtz and Noise

Extract()

std::map< std::string, double > ahdcSignal::Extract

(

bool

expression = true

)

Extract various informations from the digitized signal.

This method computes

• binMax, binOffset, adcMax, timeMax, integral
• timeRiseCFA, timeFallCFA, timeOverThresholdCFA, timeCFD

GenerateNoise()

void ahdcSignal::GenerateNoise	(	double	mean,
		double	stdev )

Generate gaussian noise.

Returns

Fill the attribut Noise

operator()()

double ahdcSignal::operator() ( double timePoint )

inline

Overloaded () operator to get the value of the signal at a given time.

Parameters

t	Time at which to calculate the signal's value

Returns

Value of the signal at the time t

SetElectronYield()

void ahdcSignal::SetElectronYield ( double electronYield_ )

inline

Set the electron yield.

Only relevant before the use of the method Digitize
