Function Documentation

exactBlackman()

template<typename realT >

void mx::sigproc::window::exactBlackman

(

std::vector< realT > &

filt

)

The Exact Blackman Windwo.

See https://en.wikipedia.org/wiki/Window_function

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Template Parameters

realT

a real floating point type

Parameters

[out]

filt

The pre-allocated vector which will store the filter
