Functions ¶
func FloatPtrEqual ¶ added in v0.26.1
func PrintFloatPtr ¶ added in v0.26.1
func ValueOrZero ¶ added in v0.26.1
Types ¶
type FilterMap ¶ added in v0.16.8
type FilterMap struct {
// contains filtered or unexported fields
}
FilterMap stores a map of high-pass filters, keyed by a unique identifier (e.g., satellite ID).
func NewFilterMap ¶ added in v0.16.8
NewFilterMap creates a new FilterMap.
type HighPassFilter ¶ added in v0.16.8
type HighPassFilter struct {
// contains filtered or unexported fields
}
HighPassFilter represents a simple real-time first-order high-pass filter. It filters out low-frequency components from an input signal, allowing high-frequency components to pass through.
func NewHighPassFilter ¶ added in v0.16.8
func NewHighPassFilter(cutoffFreq float64, samplingPeriod float64) (*HighPassFilter, error)
NewHighPassFilter initializes a high-pass filter with the given cutoff frequency and sampling rate. cutoffFreq: The cutoff frequency in Hz. samplingRate: The sampling period in seconds. Returns a pointer to the initialized HighPassFilter and an error if the input values are invalid.
func (*HighPassFilter) Apply ¶ added in v0.16.8
func (hp *HighPassFilter) Apply(inputSample float64) float64
Apply processes a single input sample and returns the filtered output.
func (*HighPassFilter) Reset ¶ added in v0.16.8
func (hp *HighPassFilter) Reset()
