Abstract: The present invention provides molded activated carbon, and the molded activated carbon is produced by molding a mixture containing powdery activated carbon (a) having a median particle size of 80 ?m to 120 ?m and a standard deviation ?g of 1.3 to 1.9 in a particle size distribution and a fibrous binder (b). The molded activated carbon of the present invention has excellent removability for free residual chlorine, volatile organic compounds, CAT, and 2-MIB and excellent turbidity filterability, and is for use as a water purifier cartridge or the like.

Abstract: Provided is an FIR filter capable of obtaining predetermined characteristics with a small number of input taps, delay circuits, and multipliers and achieving an improved response and low cost. In a low-pass filter, a band-pass filter, and a high-pass filter based on an FIR filter, a basic filter is configured that gives a basic impulse response function and has a filter coefficient determined from the impulse response function. Filters having different frequency characteristics are configured by changing the time scale or frequency scale of the basic filter. These filters having different frequency characteristics are combined in a cascade form or a step form, thereby constructing an FIR filter having a small number of taps.
