EXTERN int rf_amplify_complex	(	complexwf_t *	RF,
		double	dB
	)

Amplifies the signal by the level dB. The voltage gain is calculated:

$gain = \sqrt{ 10^{ \frac{db}{20} } }$

Parameters:

	RF	waveform to be processed
	dB	gain (or attenuation) in dB

Returns:: BPM_SUCCESS upon success, BPM_FAILURE upon failure

EXTERN int rf_phase_shifter	(	complexwf_t *	RF,
		double	rotation
	)

Rotates the phase of the signal by the amount specified

Parameters:

	RF	waveform to be processed
	rotation	phase rotation in degrees

Returns:: BPM_SUCCESS upon success, BPM_FAILURE upon failure
