A modulated signal, having a varying magnitude signal envelope, is conditioned, such as to facilitate amplification (500). Minimum values are determined values for portions of the signal envelope (520, 530), and a window expansion function applied to scale each portion of the signal envelope having a minimum value below a particular threshold, such that each scaled portion has a new minimum value of at least the particular threshold (535, 540, 550, 555). |
