Constructor & Destructor Documentation

RippleSource()

RippleSource::RippleSource	(	double	offset,
		double	frequency,
		double	sampling_rate,
		YAML::Node	ripple_duration,
		double	mean_amplitude,
		double	noise_stdev,
		bool	convert_byte_order,
		unsigned int	nchannels )

Create the source and set the user options

Parameters

offset	purely value added to the sample generated
mean_amplitude	mean of the amplitude of the ripple
frequency	frequency of the ripple should be contain between 150 and 250
ripple_duration	Yaml Node containing duration of a ripple and zero interval value in msecs. The key specify for which channel apply this set of parameters. If the key is *, apply it for all channel.
sampling_rate	rate of generating and sending samples
noise_stdev	standard deviation of the noise added to the signal
nchannels	number of channels simulated @params convert_byter_order

Member Function Documentation

Produce()

int64_t RippleSource::Produce ( char ** data )

overridevirtual

Produce sample and timestamps for each channel to package and send in the network.

Signal produced = ripple signal separated by segment of zero amplitude signal

Implements DataSource.
