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
