Title: Apparatus and method for approximating an exponential decay in a sound synthesizer
Inventor: JARIC MELITA
IPC: G10H1/057
Filed: 1998-01-17
Granted: 2000-01-01
Abstract: A linear approximation to an exponential decay function exploits the characteristic of an exponential function that, at equal time intervals, the ratio of a parameter value at the beginning of the interval to the parameter value at the end of the interval remains constant. The technique for linear approximation of an exponential decay includes selection of a constant period or interval of time and selection of a constant ratio between the parameter value at the beginning of the constant period and the parameter value at the end of the constant period. In one embodiment, the selected ratio is one-half to exploit a binary arithmetic implementation. For a ratio of one-half, the exponential decay has a ""half-life"" in which only half the parameter value at the beginning of a period is left at the end of the selected ""half-life time period"".

Title: New structure of an echo integrated circuit using DRAM
Inventor: HUANG JIN-YAN
IPC: H01L27/108
Filed: 1998-02-12
Granted: 2000-11-11
Abstract: The invention provides a new structure of the echo integrated circuit. By using dynamic random access memory (DRAM) parts as shift registers, the number of transistor in each storing cell is decreased. Additionally, there is only one single type of transistor (such as NMOS or PMOS), so the fabrication process is simplified. The size of the echo integrated circuit is reduced and the production cost is lowered drastically. Furthermore, by rearranging the time-clock signals and the storage cell array, the power source spikes of the system caused by the time clock structure are reduced. Consequently, the noise is reduced and the voice quality elevated. The noise frequency is raised at the same time, so filters with lower production cost can be used.

IPC: G11B7/125
Filed: 1998-02-26
Granted: 2000-02-21
Abstract: For application of asymmetry trial writing onto phase-change recording discs, this invention is intended to determine an optimum level of recording power accurately. Single pattern or random pattern signals are recorded, and phase differences between PLL clock edges and data edges are detected using reproduced signals to determine a threshold value of recording power where a predetermined percentage of phase differences occurs. The threshold power is then multiplied by a constant to provide a optimum level of recording power. Further, there are disclosed arrangements for determining an optimum power condition at a point where an error count (jitter) is minimized, and determining an optimum power condition as an averaged power level existing between low and high power conditions.

Title: Transmission system having a simplified channel decoder applicable to mobile phone systems for better reliability in serial transmission
Inventor: BAGGEN CONSTANT PAUL MARIE JOZEF
IPC: H03M13/39
Filed: 1998-05-29
Granted: 1999-12-21
Abstract: In a tailbiting convolutional encoder, the encoder is initialized with a sequence of symbols corresponding to the final symbols of a sequence to be encoded, resulting in that the begin state and the final state of the encoder are the same. The problem of convolutional coding obtained by such an encoder is substantial computational resources required to decode it. In the simplified decoder, according to the invention, the decoding process is extended by a plurality of trellis sections to a length N+v. At the final trellis section, the state with the largest path matrix is selected as the best state. This best state is used as starting point for a trace back operation to find an earlier state at N trellis section before the final trellis section. The earlier state found there is regarded as correct, having as consequence that the trellis should terminate also in said state. By performing a trace back from said state the source symbols could be found.
