Title: Digital filter and digital-signal filtering method
Inventor: VAN BAVEL NICHOLAS R
IPC: H03H17/02
Filed: 2002-05-02
Abstract: PROBLEM TO BE SOLVED: To provide an interpolating filter having no arithmetic operation acting by its low-accuracy FIR(finite impulse response) coefficients. SOLUTION: While a low-accuracy FIR filter performs a filtering in a digital interpolating operation, this includes a sampling-rate conversion for scattering zeros in each space between the samples of its input time series and includes a filtering step for removing the images caused by the sampling-rate conversion. The filtering coefficients of the low-accuracy FIR filter are so selected that its low-end frequency response including a pass band, a transition band, and a block band portion occurring just after the transition band completes is made nearly equal to the frequency response obtained by FIR filtering coefficients highly more accurate than the filtering coefficients.  In the low-accuracy FIR filter, a set  -1, 0, +1} comprising only three filtering coefficients is so used as to make minimum the number of non-zero filtering coefficients required to operate the output of a interpolator. Instead of that, a second low-pass filter performs the filtering of the high-frequency-image energy occurring in the output of the low-accuracy FIR filter.

Abstract: <P>PROBLEM TO BE SOLVED: To solve a conventional problem in which a finish height Ls of a stud cannot be determined accurately because of variance in the overall length of the stud in arc stud welding.  <P>SOLUTION: With the stud held in the holder of a welding gun, a contact member 2 is abutted on an object to be welded for positioning.

Simultaneously, each moving distance Lr, Lp and Ld of the stud upper end at the time of the lowering, the raising, and the re-lowering respectively are calculated. Then, on the basis of these calculation results and the reference height Lu, the finish height Ls, i.e., a distance from the object to the stud upper end after completion of the welding, is determined from the expression of (Lu-Lr+Lp-Ld) in this method.  <P>COPYRIGHT: (C)2004,JPO
