Title: Data transmission system
Inventor: KUBO YASUSHI
IPC: H04L25/49
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To include the length of an encoded bit string within the specific range of original source data and to improve transmission efficiency as compared with a case using biphase codes by analyzing the bit pattern of source data and preferentially allocating a short code word to a pattern having high appearance frequency. SOLUTION: In the case of transmitting data by binary codes of '0' and '1', data (source data) expressed by binary codes are distinguished in each four bits and how many times the same bit pattern is repeated is detected. Prescribed code words are preferentially allocated to bit patterns in accordance with the repeated frequency to convert the source data into code word data. A code allocating rule indicating which original binary code corresponds to each 4-bit code word data is added to the code word data and transmitted. Consequently the deterioration of transmission characteristics can be prevented similarly to biphase codes and the code length can be included within a range from about a half of source data up to about 1.3 times.

Filed: 1986-10-24
Abstract: PURPOSE:To measure impedance stably by supplying a current which flows through an element to be measured to a parallel of a resistance and a capacitor having specific values respectively and calculating the impedance value of the element from measured values of a measured voltage and a voltage for current measurement. CONSTITUTION:A bridge circuit constituted by adding a parallel capacitor 43 to a reference resistance 4 is used to reduce the influence of internal noises of an input amplifier. Further, un stable bridge circuit operation based upon frequency characteristics of an amplifier is eliminated. The output voltage of this bridge circuit is measured while decomposed into a measurement signal and an in-phase and an orthogonal component, and then digitized, and the influence of the added capacitor 3 is removed to find a value of admittance to be measured. Consequently, a stable, high-accuracy measurement is taken even in environment where a measuring instrument needs to be connected to the element to be measured by using a long cable.
