The electro-optical rangefinder (1) has transmitting unit (3) provided with laser diode (30) and laser diode driver (31) for transmitting intensity modulated optical radiation (4), particularly as burst-modulated radiation with burst rate, burst duty cycle and pulse frequency within burst. An input filter (11) is a time-discreetly and value-continuously implemented digital filter structure. The input filter is provided with a time quantizing scanning switching stage for reception signal, a weighting stage of analog amplitude values, an analog summation stage and a time-discrete output stage. Independent claims are included for the following: (1) an electronic receiver chip with an input filter; and (2) a method for measuring distance. |
