Functions
double	r8b::convertResponseToLog (const double re, const double im)
	Converts complex response into magnitude in log scale.
void	r8b::findFIRFilterResponseLevelRtoL (const double *const flt, const int fltlen, const double maxg, double &th, const double thend)
	Locates normalized frequency at which the specified maximum filter gain is reached.
void	r8b::findFIRFilterResponseMaxLtoR (const double *const flt, const int fltlen, double &maxg, double &maxth, const double thend)
	Locates normalized frequency at which the maximal filter gain is reached.
void	r8b::findFIRFilterResponseMinLtoR (const double *const flt, const int fltlen, double &ming, double &minth, const double thend)
	Locates normalized frequency at which the minimum filter gain is reached.
void	r8b::updateScanStep (double &step, const double curg, double &prevg_log, const double prec, const double maxstep, const double minstep=1e-11)
	An utility function that performs frequency response scanning step update based on the current magnitude response's slope.
