PURPOSE: A method for deleting direct current is provided to remove direct current components of electronic signals, by passing signals, when a high band passing filter, having a threshold frequency made by a capacity and a resistor, is over a threshold frequency. CONSTITUTION: A method for deleting direct current of electronic signals comprises the steps of: having transmission characteristics supplying more than one number of zero point by a predetermined frequency called as a cut frequency; delivering transmission characteristics as same as an absolute value of the cut frequency in a delivering volume; and making electronic signals flow via the filter.
