摘要
A method and an apparatus for leveling an increasing or decreasing slope of an AM modulated receiving signal attenuate the AM modulated receiving signal with an attenuation curve with a stepwise slope corresponding to the increasing or decreasing slope of said AM modulated receiving signal, filters the attenuated AM modulated receiving signal within AM-demodulation with a lowpass infinite-impulse-response filter of at least second order and increases the level of each delay-unit's output signal of the infinite-impulse-response filter each time a step in the attenuated AM modulated receiving signal arrives at the input of said infinite-impulse-response filter.
