Title: Decoding method
Inventor: TAKATSU KAZUNORI
IPC: H04L27/34
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To execute max. likelihood decoding with high precision by judging a convolution-encoded reception signal group based on likelihood found by the occurrence probability of a signal point itself so as to decode it. SOLUTION: A signal point occurrence probability calculating part 20 for calculating the occurrence probability (S) of the signal point itself is provided in addition to the configuration of a general viterbi decoder. A signal point occurrence probability calculating part 20 counts the judged signal points, adopts frequency information which is normalized and generated by the number of previously received signal points as the signal point occurrence probability and calculates its logarithm. A branch metric is calculated as r<2> /2σ<2> -1ogP(S). 'r' is distance between a transmission signal point and a reception point and inter-code interference and noise follows a Gauss distribution.  An addition comparison selecting part 16 adds the obtained branch metrics to path metrics in the respective preserved states in a memory 14 based on various kinds of combinations, the combination of the branch metric and the path metric, which makes a max. value, is stored in the memory 18 as residual path information and a path selecting part 19 selects a max. likelihood path from them.

Title: Automatic accompaniment apparatus
Inventor: KATOU HIROSHI
IPC: G10H1/36
Filed: 1977-10-01
Abstract: PURPOSE: To prevent the occurrence of discontinuity and interruption of accompaniment tones by reading out the pitch name signals and attack signals having been stored in ROM and storing these in a latch circuit.  
     CONSTITUTION: As a play switch SWa is closed, the trigger signal through a delay circuit 116 and a NAND circuit are generated to reset two sets of counters which are formed by FFs 102 thru 105, FFs 106 thru 110 and count clocks. According to the count values of the FFs 106 thru 110, the binary pitch name signals relate to C-major chords and octave signals having been stored in ROM 32 corresponding to the selected rhythms through a priority circuit 117 are subsequently read out in synchronization with the clocks. These signals having been read out are held stored in the D type FFs 121 thru 124 of a latch circuit 36 until the switch SWb is again closed after having been opened and the next attack signal through the NAND gate 113 is generated. Hence, the accompaniment tones based on the pitch name signals by the storage contents of the circuit 36 are formed without discontinuity and interruption even at the new rhythm selection

Abstract: PURPOSE:To facilitate the mount of additional function to be executed in response to engine revolutions exerting influence on an audio device and the like by forming a parallel pattern and a roughly perpendicular pattern with respect to a pattern for a power supply formed in a board. CONSTITUTION:In an engine revolution detector 10, its patterns 10a and 10b are formed in a layer identical to a power supply line 20 formed in a board while being closely attached. In the detector 10, the patterns are formed in such a way that the pattern 10a formed in parallel with the power supply line 20 and the pattern 10b formed roughly perpendicular with respect to the power supply line 20 are alternately connected while being raged.

Title: Sample holding circuit
Inventor: NISHIMURA TOSHIJI
IPC: G11C27/02
Filed: 1980-08-29
Abstract: PURPOSE:To obtain a sample holding circuit which has a reduced amount of leakage of the sample holding pulse and can perform a high-speed operation with a small amount of power consumption, by controlling the supply of the input signal via a complementary transistor and at the same time controlling the sample holding to a capacitor with a high-input impedance element. CONSTITUTION:Complementary transistors 28A and 28B constituting a gate are switched via a pair of N type transistors 24A and 24B which receive the application of the contrary sample holding pulse at the base respectively. Then the supply of the input signal is controlled for a sample holding capacitor 29 connected with an FET30 of high input impedance. Thus the input signal and the sample holding pulse are transmitted through an unbalanced signal system and a balanced signal system respectively. At the same time, the leakage of the sample holding pulse is reduced by a high input impedance FET. Furthermore the dynamic range is increased owing to the use of the complementary transistors to realize a high-speed operation, and at the same time no current flows to the complementary transistors in the cut-off mode to reduce the power consumption.
