ABSTRACT:
A filter can estimate the signal in an observed input having signal and noise. The filter has a level device and a feedback device. The level device has an input and output terminal for providing on the output terminal a rescaled output variably proportional to the input on the input terminal. This level device can repetitively change the variable proportions between its input and output terminal. The feedback device is coupled between the output and input terminal of the level means for applying to the input terminal an input proportional to the difference between the observed input and the output on the output terminal.
