MHAFilter::transfer_function_t::transfer_function_t ( )

inline

Default constructor for STL conformity.

Not used.

Member Function Documentation

partitions()

unsigned int MHAFilter::transfer_function_t::partitions ( unsigned int  fragsize ) const

inline

for the given partition size, return the number of partitions of the impulse response.

Parameters

fragsize

partition size

Returns

number of partitions occupied by the impulse response

non_empty_partitions()

unsigned int MHAFilter::transfer_function_t::non_empty_partitions ( unsigned int  fragsize ) const

inline

for the given partition size, return the number of non-empty partitions of the impulse response.

Parameters

fragsize

partition size

Returns

the number of non-empty partitions of the impulse response, i.e. partitions containing only zeros are not counted.

isempty()

bool MHAFilter::transfer_function_t::isempty ( unsigned int  fragsize, unsigned int  index  ) const

inline

checks if the partition contains only zeros

Parameters

fragsize	partition size
index	partition index

Returns

true when this partition of the impulse response contains only zeros.
