Trigger Realization

TriggerRealizations are generated once per SimulatedDrop for each unique TriggerModel and contain information about the synchronized simulated devices’ assumed time offsets.

class TriggerRealization(num_offset_samples, sampling_rate)

Bases: Serializable

Realization of a trigger model.

A trigger realization will contain the offset between a drop start and the waveform frames contained within the drop.

Parameters:

• num_offset_samples (int) – Number of discrete samples between drop start and frame start

• sampling_rate (float) – Sampling rate at which the realization was generated in Hz.

Raises:

• ValueError – For num_offset_samples smaller than zero.

• ValueError – For a sampling_rate smaller or equal to zero.

classmethod Deserialize(process)

Deserialize an object’s state.

Objects cannot be deserialized directly, instead a Factory must be instructed to carry out the deserialization process.

Parameters:

process (DeserializationProcess) – The current stage of the deserialization process. This object is generated by the Factory and provides an interface to deserialization methods supporting multiple backends.

Return type:

TriggerRealization

Returns:

The deserialized object.

compute_num_offset_samples(sampling_rate)

Compute the number of realized offset samples for a custom sampling rate.

The result is rounded to the nearest smaller integer.

Parameters:

sampling_rate (float) – Sampling rate of intereset in Hz.

Return type:

int

Returns:

The number of trigger offset samples.

Raises:

ValueError – For a sampling_rate smaller or equal to zero.

serialize(process)

Serialize this object’s state.

Objects cannot be serialized directly, instead a Factory must be instructed to carry out the serialization process.

Parameters:

process (SerializationProcess) – The current stage of the serialization process. This object is generated by the Factory and provides an interface to serialization methods supporting multiple backends.

Return type:

None

property num_offset_samples: int

Number of discrete samples between drop start and frame start.

property sampling_rate: float

Sampling rate at which the realization was generated in Hz.

property trigger_delay: float

Time between drop start and frame start in seconds.
