Abstract
A time-discrete picture signal is formed from an analog picture signal, such as a luminance signal or a chrominance signal. Corresponding to the time-discrete picture signal, a time-discrete filter signal is formed, specifically a so-called 'peaking signal,' which has a sequence of peaking signal values, of which one value each is associated with one signal value of the time-discrete picture signal. The discrete peaking signal is formed by a digital peaking filter from the discrete picture signal or by an analog peaking filter from the analog picture signal during subsequent sampling of the analog peaking signal. The peaking filter increases the amplitude of selected frequency components of the picture signal.
