What actually captured a signal -- an electrode, transducer, etc.

• bsml:Electrode ^c

The class or type of signal (e.g. EEG, ECG).

A computer simulation or modelling process that created the Signal or Recording.

The source (i.e. device, simulation, etc) of a Signal or Recording.

• bsml:Device ^c
• bsml:Simulation ^c

Some measurement of time, either a particular point in time or some interval.

• bsml:Instant ^c

A device that converts a measurable quantity into an electrical signal (e.g. thermistor, pressure sensor, strain gauge).

A signal that has been sampled at a constant rate.

• bsml:period ^dp
• bsml:rate ^dp

The sampling coordinates associated with a signal's data values.

The location of actual data, in a format suitable for computer processing.

The class or type of an Event.

Pre-filtering applied to a signal as part of collection.

The Recording a Signal is part of.

What was used to collect or derive an electrical signal.

A signal's generic type.

• A semantic tag given to a resource by an annotation.

• Tags are effectively controlled keywords.

An instant or interval associated with a resource.

A resource describing the measurement uncertainty associated with a Recording, Signal, or Segment.

The binary-bit resolution of the analogue-to-digital convertor or sampling device used to digitise the signal.

The cutoff frequency in Hertz, of a filter.

The 0-origin position of a signal in a physical recording.

The maximum frequency in Hertz, contained in the signal.

The maximum value of the signal.

The minimum frequency in Hertz, contained in the signal.

The minimum value of the signal.

The temporal offset in seconds, from the beginning of a recording to a signal's first sample.

The sampling period in seconds, of a uniformly sampled signal.

The sampling rate in Hertz, of a uniformly sampled signal.

The resolution in seconds, of a clock's timing.

• The physical units that are represented by a signal's data values. Units are to described using codes from the Unified Code for Units of Measurement (UCUM) code system.

• Specification of units allows for consistency checking and automatic conversion.
