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. |
