Constructor & Destructor Documentation

UserAnalogFilter::UserAnalogFilter (  unsigned int    kernel_length = 10, double *    weights = 0 )

Constructs a new user-defined analog filter. Parameters: kernel_length  The length of the filter kernel. weights  An array of filter-weights. These weights are not normalized, so make sure that they sum up to 1, if you want to create a low-pass filter.

UserAnalogFilter::~UserAnalogFilter (  void    )

Free the memory.

Member Function Documentation

void UserAnalogFilter::createKernel (  unsigned int    n )  [virtual]

Calculates a new kernel for the given number of data points. If n is not equal to the kernel-length, then the last n weights of the user-defined kernel are used. Their sum is normalized to the sum of the whole kernel. Parameters: n  Number of data points to filter. Implements AnalogFilter.

int UserAnalogFilter::updateInternal (    )  [virtual]

Updates the internal state of the filter. Reimplemented from AnalogFilter.

double UserAnalogFilter::m_sum_kernel [private]

Sum of all kernel weights.
