Function Documentation

complex_exp_gen()

void complex_exp_gen	(	own::span< std::complex< float >>	_dest,
		double	_f,
		double	_fs
	)

This function generates a complex exponential in _dest.

complex_exp_gen_conj()

void complex_exp_gen_conj	(	own::span< std::complex< float >>	_dest,
		double	_f,
		double	_fs
	)

This function generates a conjugate complex exponential in _dest.

hex_to_binary_converter()

void hex_to_binary_converter	(	own::span< int32_t >	_dest,
		char	_from
	)

This function makes a conversion from hex (the input is a char) to binary (the output are 4 ints with +1 or -1 values).

resampler() [1/2]

void resampler	(	const own::span< float >	_from,
		own::span< float >	_dest,
		float	_fs_in,
		float	_fs_out
	)

This function resamples a sequence of float values.

resampler() [2/2]

void resampler	(	own::span< const std::complex< float >>	_from,
		own::span< std::complex< float >>	_dest,
		float	_fs_in,
		float	_fs_out
	)

This function resamples a sequence of complex values.
