In this paper, several special problems about walsh functions have been reviewed on the basis of their bi-valued behaviour. On the sequence-ordering problem, the conversion rules among the sequoncy ordering, binary ordering, and the Hadamard -matrices ordering have been given. On the time shift problems, the significance of the new concept of dyadic time has been interpreted. Besides, the problems of spectral sequency analysis and the resonance of non-sinusoidal wave have been discussed. The purpose...

The results of an actual X-band rectangular waveguide phase controlled antenna array are given. Using the antenna array as boundary values of electro-magnetic field, a solution of the field equations is made, and an integral equation of the tangential electric feild function of an unknown aperture is established. Through conversion to matrix methods, numerical results are obtained by using the DJS-6 computer. A sourceless small array containing 115 elements was made. The directional diagram of the array element was measured. Also two magnetic H face waveguide simulators: HIC 14℃ and HIC 29℃ were made, and experimental tests were performed. The parameters of the wide angled matching dielectric plate and the matching foil over the aperture were determined by theoretical calculations and experimental results are quite close to each other. On the 8600-9600 MHz band and ±60℃ scanning spherical cone; the VSWR of input voltage on the antenna is less than 2.

This paper discusses a new voice-data multiplexing transmission system which can transmit data signals along a telephone line so that the speakers can get remote hand-written texts or diagrams when a conversation is going on. This system uses time assignment method to multiplex (interpolate) voice and data signals and then transmits them along the same channel. Compared with the usual frequency division system, this system can improve the transmission qualty. Another feature of this system is that it possesses the capability of on-line identification, that is, data and voice signals can be idsntified and dispatched in real time according to their inherent features. As a result of no identification signal, this sysem can raise the efficiency of telephone channel.In this paper,a new method of on-line identification (conversion and cascade method) , which was at first proposed for this system, is described.This method simplifies the system with higher accuracy.

本文探讨的是一种新的话音——数据混合传输系统。它可以在通话同时传送数据信号,使对话双方能及时见到所讨论的数据、文字与图形。本系统特点之一是采用时间分配体制解决两种信号通过同一信道传输的问题。即在话音间隙中传送数据。由于每种信号均可占用全部电话频段,与已有的频分系统相比能改善信号传送质量。本系统的另一特点是具有在线识别功能,在发送端无须发送附加的标志信号,接收端根据话音与数据的特点实时地在进行识别与分遣,从而提高了信道利用率。文中介绍了一种新的在线识别方法(变换——分步法),它具有线路简单和识别准确的特点,是作者为解决本系统中两种信号的识别问题而提出的。
