Title: Signal processor
Inventor: KURODA ICHIRO
IPC: H03H17/02
Filed: 1986-10-31
Abstract: PURPOSE:To accelerate the operation of a non-cyclic digital filter where coefficients are symmetrical by inputting the added result of two outputs from a two-port memory storing past input signal trains in a multiplication circuit. CONSTITUTION:When the non-cyclic digital filter where the coefficients are symmetrical is realized by a signal processor, a signal x(i) and a signal x(N-1-i) which are stored in the two-port memory are simultaneously fetched and added and the added result x(i)+x(N-1-i) is multiplied by a filter coefficient h(i) stored in a coefficient memory so as to execute the cumulation in terms of the multiplied result h(i){x(i)+x(N-1-i)}. Now, if the degree of the filter is even, (i) is cumulated N/2 times from zero to N/2-1. Meanwhile, if the degree of the filter is odd, (i) is cumulated (N+1)/2 times from zero to (N-1)/2. But since the term of h(N-1)/2X(N-1)/2 is duplicately added, 0.5h(N-1)/2 is stored in the coefficient memory instead of h(N-1)/2.

IPC: G06K9/20
Filed: 1985-11-20
Abstract: PURPOSE:To improve the reading position precision by installing a mechanism for correcting the transport error from the optically readed results for the marks on a medium which keeps a standard distance. CONSTITUTION:Marks 201 and 202 are printed, keeping a prescribed interval, onto a medium, and an optical reading part 106 performs reading operation along a reading center line 203, and the results are memorized into the memory part 108 in a control processing part 101. A control processing part 101 searches the optically readed results memorized into the memory part 108 and detects the mark 201 at the head part of the medium, and sets said mark as a reading standard position. Then, the mark 202 is detected by searching the vicinity of the standard position on the optically readed results of the mark 202, and the number of times of optical reading ranging from the mark 201 and 202 is calculated, and the transport quantity error in the reading at this time is calculated from the difference between the number of times of standard optical reading which is previously calculated, and the transport quantity error is corrected according to said error. Thus, the precision for the optical reading position is improved.
