DerivativeFilter.h
Provides a DerivativeFilter class for calculating the rate of change of input values.

DerivativeFilter::previousReading
float previousReading
Stores the previous input value for calculating the rate of change.
Definition DerivativeFilter.h:30

DerivativeFilter::GetOutput
float GetOutput()
Retrieves the current filtered derivative output.
Definition DerivativeFilter.cpp:5

DerivativeFilter::DerivativeFilter
DerivativeFilter()
Constructs a DerivativeFilter instance with default configurations.
Definition DerivativeFilter.cpp:3

DerivativeFilter::outputValue
float outputValue
Stores the most recent filtered derivative value.
Definition DerivativeFilter.h:31

DerivativeFilter::Filter
float Filter(float value)
Filters the derivative of the input value and normalizes the output.
Definition DerivativeFilter.cpp:9

DerivativeFilter::minFilter
MinFilter< 40 > minFilter
Minimum filter for baseline normalization.
Definition DerivativeFilter.h:29

DerivativeFilter::output
RunningAverageFilter< 10 > output
