The IBDA_FrequencyFilter interface is implemented on a BDA tuner device, and is used by the Network Provider to tell the tuner how to set its frequencies.
In addition to the methods inherited from IUnknown, the IBDA_FrequencyFilter interface exposes the following methods.
| Method | Description |
| get_Autotune | Retrieves a channel frequency to scan for a precise signal. |
| get_Bandwidth | Retrieves the bandwidth parameters. |
| get_Frequency | Retrieves the frequency parameters. |
| get_FrequencyMultiplier | Retrieves the frequency multiplier parameters. |
| get_Polarity | Retrieves the polarity parameters. |
| get_Range | Retrieves the range parameters. |
| put_Autotune | Specifies a channel frequency to scans for a precise signal. |
| put_Bandwidth | Specifies the bandwidth parameters. |
| put_Frequency | Specifies the frequency parameters. |
| put_FrequencyMultiplier | Specifies the frequency multiplier parameters. |
| put_Polarity | Specifies the polarity parameters. |
| put_Range | Specifies the range parameters |
