Abstract
The invention relates to a filter device () for detecting and/or removing erroneous components like noise, deformations, glitch components or other errors in and/or from a signal, to a demodulation device using the filter device, to an information transmission system using the demodulation device and to a method for detecting a noise impulse in an input signal (Cα(t), Cα[k]). The filter device includes a summing element (-N,) connected to a correction element (). The summing element (-N,) sums the input signal (Cα(t), Cα[k]) within a reference interval (N) and the correction element () verifies the summed input signal (IS[k]) with at least one signal condition (, N+1, ΔCα[k]). Finally, the correction element () outputs a predetermined signal (Cα[k]) based on the result of the verification between the summed input signal (IS[k]) with at least one signal condition (, N+1, ΔCα[k]). The foregoing filter device is able to remove noise from an input signal. This stabilizes the input signal against environmental influences occurring e.g. during signal transmission.
