Constant Gain¶

class Gain(gain=1.0, rescale_quantization=False)[source]¶

Constant gain model.

Parameters:

gain (float) – Linear signal gain to be applied before ADC quantization. Unit by default, meaning no gain adjustment.
rescale_quantization (bool) – If enabled, the quantized signal is rescaled to the original signal range before gain adjustment. Disabled by default.

classmethod Deserialize(process)[source]¶

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:: Gain
Returns:: The deserialized object.

estimate_gain(input_signal)[source]¶

Estimate the gain required to adjust the signal to the ADC input range.

Returns: Linear gain to be applied to the input_signal’s Voltage samples.

serialize(process)[source]¶

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 gain: float¶

Linear gain before ADC quantization.

Quantizer operates by default between -1. and +1. Signal can be adjusted by to this range by appropriate gain setting.

Returns: Gain in Volt.
