	This event variable will be increased by 1 whenever a UDP packet is received by the signal source. Thus, longer periods of missing packets may be detected by observing the time course of the <tt>NatusPackageCount</tt> event.

			=== SampleLost ===
			''SampleLost'' is represented by 1 bit. The device sends data in sample packets over UDP connection which is not a reliable connection and hence may result in loss of some. The lost packets between two packets received from the device are detected from the packet counter, and inserted with a value of NaN. The ''SampleLost'' state value is 1 if the sample has been lost, and 0 if the packet is received from the device.

	=== Interpolated ===		=== Interpolated ===
	Interpolated is ~~represented by 1 bit~~. The ~~device sends data in packets over UDP connection which is not a reliable connection~~ and ~~hence~~ may result in loss of some packets. The lost packets between two packets received from the device are linearly interpolated from the aforementioned two packets. The Interpolated state value is 1 if the packet is interpolated or 0 if the packet is received from the device.		''Interpolated'' is an obsolete name for ''SampleLost''. The ''Interpolated'' state has been kept for backward compatibility and may be removed any time.
