The phase response of a passband waveform at the receiver is given by
$$\varphi \left( f \right) = - 2\pi \alpha \left( {f - {f_c}} \right) - 2\alpha \beta {f_c},$$
where fc is the centre frequency, and α and β are positive constants. The actual signal propagation delay from the transmittance to receiver is

A. $${{\alpha - \beta } \over {\alpha + \beta }}$$

B. $${{\alpha \beta } \over {\alpha + \beta }}$$

C. α

D. β
