IBDA_SignalStatistics Interface

The IBDA_SignalStatistics interface is implemented on a BDA device filter and provides methods by which the filter can describe the condition of a signal that is being received. In addition to the methods inherited from IUnknown, the IBDA_SignalStatistics interface exposes the following methods.

Method	Description
get_SampleTime	Retrieves the sample time used to measure the signal.
get_SignalLocked	Retrieves a Boolean value indicating whether the signal is locked.
get_SignalPresent	Retrieves a Boolean value indicating whether a signal is present.
get_SignalQuality	Retrieves a value from 1 to 100 indicating the quality of the signal.
get_SignalStrength	Retrieves a value that indicates the strength of the signal in decibels.
put_SampleTime	Specifies the sample time used to measure the signal.
put_SignalLocked	Specifies whether the signal is locked.
put_SignalPresent	Specifies whether a signal is present.
put_SignalQuality	Specifies the quality of the signal.
put_SignalStrength	Specifies the strength of the signal in decibels.
