Title: Method for designing fir filter
Inventor: KIKUCHI ATSUSHI
IPC: H03H17/06
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To design the finite impulse response(FIR) filter high in precision without increasing number of taps even when a transition area is narrow. SOLUTION: In the case of a band pass filter employing an FIR filter, for example, a slope of attenuation toward lower frequencies is steeper than that toward high frequencies, many number of taps are required for approximation with high precision. Then for the design method through cosine transformation, interval of frequencies in a frequency range is made finite at a frequency range desiring to increase the precision by adding equations to the transformation. There are a method of adding equations under the condition of minimizing a change in a tap coefficient from tap coefficients obtained by the cosine transformation and a method of solving the original cosine transformation equations and the added equations altogether through the least square method. Since the frequency interval is partially made fine, the filter with high precision is designed without increasing number of taps.

Abstract: PURPOSE:To filtrate carbon particles in the exhaust gas nicely for a long period of time by a method wherein a plurality of filtrating units, consisting of a main exhaust gas flowing pipeline, equipped with frustoconical inner walls whose diameters are reduced lengthwisely, and an annular filtrating member, fitted to the outer periphery of the pipeline, are connected in series. CONSTITUTION:In case a part of the exhaust gas, discharged through an exhaust gas collecting pipe 4, is recirculated into a suction system through a filtrated exhaust gas outlet port 8 connected to a suction pipe, a part of the carbon particles in the exhaust gas collide against the frustoconical inner walls provided in the main exhaust gas flowing pipelines 1a-1c and advance along the surfaces of the walls without changine the advancing directions thereof. On the other hand, the flow of the exhaust gas is changed to the flow along the radial directions of the pipelines at the outlets of the opening ends which are the small diametral sides (outlet sides) of each pipelines 1a-1c. In this case, the exhaust gas moves toward the recesses 21 of the filtrating members 2a-2c under accompanying said carbon particles. Next, when the exhaust gas is passing through the filtrating members 2a-2c, the carbon particles are filtrated and are oxidized by a high-temperature circumstance thereby being eliminated as carbon diexide.
