Crest factor method for altering the crest factor in a time-discrete signal formed by a signal vector's time-consecutive signal value calculates a correcting vector to add to the signal vector

摘要

A first Fourier transformer (4) delivers a signal vector (y) in a time range that has a prefix in a parallel/serial converter (5) and is transmitted in a time range in series as an expanded signal vector to run through a digital high-pass filter (18), in which spectral portions are removed in a lower frequency range used to transmit telephone conversations via a telephone line. An independent claim is also included for a device for altering the crest factor in a time-discrete signal formed by a signal vector's time-consecutive signal values.
