Abstract
The invention describes two alternative methods and corresponding devices for producing an energy signal y.sub.n whose amplitude values represent the energy of an electrical signal s.sub.n. A first method and the corresponding device calculate the energy signal y.sub.n according to the equation ##EQU1## while a second method and the corresponding device are based on the equation, ##EQU2## where tau is a specified parameter and n represents the clock pulse.
