Abstract
An apparatus and a method for processing a signal, and for estimating a point corresponding to a maximum slope from an envelope of an input signal, are provided. A signal processing apparatus includes an envelope detecting unit configured to detect an envelope of an input signal. The signal processing apparatus further includes a correcting unit configured to correct slopes, each of the slopes being between respective points of the envelope, based on information on a clipping interval of the envelope. The signal processing apparatus further includes an estimating unit configured to estimate a point, of the envelope, in which a corrected slope, among the corrected slopes, includes a maximum value.
