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.

Member Data Documentation

double UserAnalogFilter::m_sum_kernel [private]

Sum of all kernel weights.
