const SignalHeader *

sig_hdr

)

Constructor.

Channel length is initialized to channel's samples_per_record.

Member Function Documentation

void gdf::Channel::addSamplePhys

(

const double

value

)

Add a physical sample to the channel.

value is scaled from [phys_min..phys_max] to [dig_min..dig_max] and converted to the channel's data type

Definition at line 205 of file Channel.cpp.

Here is the caller graph for this function:

template<typename T >

void gdf::Channel::addSampleRaw

(

const T

rawval

)

Add a raw sample to the channel.

value is converted to the channel's data type. but otherwise remains unmodified

Definition at line 119 of file Channel.h.

Here is the caller graph for this function:

void gdf::Channel::blitSamplesPhys	(	const double *	values,
		size_t	num
	)

Blit a number of physical samples into channel.

values are scaled from [phys_min..phys_max] to [dig_min..dig_max] and converted to the channel's data type

Definition at line 230 of file Channel.cpp.
