The invention refers to a flat spectrum signal processing system comprising a first frequency converter (12), which changes a first signal frequency (f 2 ) to a second frequency (f 1 ), an analog/digital converter (13), which converts an analog signal (s a ) to a digital signal (s d ), a filter (14), which is digital and adaptive, a digital/ analog converter (15), which converts the digital signal (s d ) to an analog signal (s a ); and a second frequency converter (16), which returns the analog signal(s a ) to the first frequency (f 2 ). According to the invention the filter (14) adaptively flattens the signal spectrum. |
