rate()

virtual void satcat5::ptp::Filter::rate ( s64  delta_subns, u32  elapsed_usec  )

inlinevirtualinherited

Optional handler for fast-acquisition; override if required.

Upstream controller provides estimated rate (i.e., rise/run). The "elapsed_usec" parameter will be between 10^5 and 10^7. Child class MAY override this method.

Reimplemented in satcat5::ptp::LinearPrediction, satcat5::ptp::ControllerLR_Inner, satcat5::ptp::ControllerPII, and satcat5::ptp::ControllerPI.

reset()

template<unsigned MAX_ORDER>

void satcat5::ptp::MedianFilter< MAX_ORDER >::reset ( )

inlineoverridevirtual

Flush previous inputs and reset to a neutral state.

Child class MUST override this method.

Implements satcat5::ptp::Filter.

Definition at line 195 of file ptp_filters.h.

update()

template<unsigned MAX_ORDER>

s64 satcat5::ptp::MedianFilter< MAX_ORDER >::update ( s64  next, u32  elapsed_usec  )

inlineoverridevirtual

Method called for each new input sample.

Input or output of INT64_MAX indicates the sample should be discarded. Otherwise, return the resulting output sample. The "elapsed_usec" parameter will be between 10^3 and 10^6. Child class MUST override this method.

Implements satcat5::ptp::Filter.
