The main purpose of this paper is to propose a new method for generating music signal by microprocessor . The use of microprocessor to generate music is by no means a new innovation. But, they use software Delay Loop for generating music signal . An attempt for generating music by programmable timer in VIA is tried in this paper. This method has several advantages; 1) Duration argument is not affected by frequency argument . In case of using Software Delay Loop , it is affected. 2) Only one address is sufficient for memorize duration argument. In case of Software Delay Loop , at least two addresses are required . 3) There is a little noise in the signal. In case of Software Delay Loop, there is a lot of noise when the program passes the loop.

晋達福 圓光大學校 1983 論文集 Vol.17 No.2

이 논문은 Intersil社에서 발표한 IM 6100 CMOS 基本 시스템을 바탕으로 하여 汎用마이크로컴퓨터를 설계한 것이다. 3K워어드 RAM의 설계, WAIT回路의 설계, 110 BAUD 터어미널의 인터페이스, 그리고 D/A,A/D變換回路 등을 다루었다. 이렇게 설계한 IM 6100 마이크로컴퓨터시스템을 ODT모니터프로그램하에서 동작시킨 결과 동작속도를 제외한 모든면에서 PDP-8E에 맞먹는 우수한 시스템임을 확인할 수 있었다. The main purpose of this paper is to design a general purpose CMOS microcomputer using IM 6100 and its family. IM 6100 CMOS Microcomputer Basic System (Fig.1) has been published by Intersil Inc. But, it lacks in its memory capacity, in its WAIT circuit, in its interface to 110 baud terminal, and in its D/A,A/D conversion circuits. The 3K word memory which is largest one without using Extended Memory Control Hardware is designed in this paper. Several circuits for making WAIT signal are proposed in this paper. 20 mA Relay Loop, 20 mA RCV Loop, 20 mA TMIT Loop, and UART timing circuits for interfacing to 110 baud terminal are discussed in this paper. Finally, D/A conversion circuits and A/D conversion circuits for controlling external devices are also designed in this paper.

Analog computer용 Op Amp 에 있어서 Drift에 의한 연산오차

진달복,채원석 원광대학교 공업기술개발연구소 1988 工業技術開發硏究誌 Vol.8 No.-

Abstract When the system is a simple single-loop linear device, the analysis may be performed in a straight forward manner by any of the methods which are well known as frequency response response, transient respanse and transfer function etc.. However. when the system is multiloop, the effect on the over-all performance that is produced by variation of an inner loop parameter is laborious and time-consuming to obtain. In such a system the effect on the out-put response that is produced by the variation of any parameter becomes extremely difficult to determine. Even when preliminary desist indicate the disirable ranges for sereral adjustable quantities, it is defficult to determine the best values for each of these quantities by analyitcal methods. This problem can be solved by the use of the analog computer which show directly the effect of parameter changes on the output response. ( The problem can be solved by the use of the digital computer. Each has its particular advantages. depending on the number of operations that must be performed by the computer and the accuracy desired. But I will take about the analog computer) Though the analog computer can be used to solve complex problems. It follows some error. The principle sources of errors are as following. ① Drift voltage in the amplifier ② Grid current at the amplifier input ③ dynamic errors. Of these, the error by drift voltage will be taken.

電子式卓上計算機에 있어서의 磁歪 遲延線에 의한 表示레지스타에 의한 考察

晋達福 朝鮮大學校 工科大學 1973 論文集 Vol.2 No.-

The purpose of this paper is to investigate some properties of magnetostriction delay line of ectronic calculator. The wave occurring in the nickel delay line when pulse inputs are given to the transmission coil of shift resister, is dealt with from the mathematical point of view. The delay time of nickel delay line is measured with Heath universal digital instrument(Eu-805), and the length of delay line for certain memory capacity is calculated. It is resulted that the length of delay line is proportional to memory capacity and that it is inverse proportional to main frequency. The tempersture effect on the day line is also investigated.

진달복,김성곤 한국정보통신학회 2004 한국정보통신학회논문지 Vol.8 No.4

this paper is to propose the formative Korean accentuation rule for the korean tort to speech conversion. The accentuation rule is as following: (1) If the rhyme of first syllable is -v, then accent is on the next syllable. (2) If the rhyme of first syllable is not -v, then accent is on the first syllable. 본 논문은 한국어 문서로부터 음성을 합성해 낼 때 액센트를 자동적으로 만듬으로써 보다 명료하고 자연스러운 회화음을 내기 위한 형식화된 액센트 규칙을 제안하는 데 그 목적이 있다. 이 규칙은 이호영님의 액센트 규칙으로부터 이끌어 낸 것으로서, 그 내용은 다음과 같다. (1) 첫 음절의 음운(rhyme)이 -v인 경우에는 그 다음 음절에 액센트가 온다. (2) 첫 음절의 음운(rhyme)이 -v가 아닌 경우에는 첫 음절에 액센트가 온다.

진달복,이현희,이영석 한국정보통신학회 2002 한국정보통신학회논문지 Vol.6 No.8

본 논문에서는 이차 Ni-Cd 팩 전지를 40분 안에 충전시키는 빠른 충전 알고리즘에 관한 연 구를 수행하였다. 제안된 알고리즘은 충전 전압과 전류를 고려해서 4가지 상태의 알고리즘을 사용한다. 이차 팩 전지가 균등충전이 일어나도록 알고리즘을 구성하였다. 이 알고리즘은 짧은 시간에 충전이 가능하게 하며, 발열 효과를 억제하고 전지의 수명을 연장시킨다. 실험결과 Ni-Cd 이차 팩전지는 40분 안에 충전되었으며, 약 2(in회 정도의 충.반전 수명을 가질 수가 있었다. In this paper, a high speed charging algorithm that charges Ni-Cd secondary pack battery within 40 minutes is implementation. Proposed algorithm is that suppling 4 stage pulse instead of constant voltage or current. That makes charge time short, temperature low, and extends battery life. Experimental results show that secondary pack battery is charged within 40 minutes and achieved life time about 2000 cycle.

The purpose of this study is to develop the speaker recognition system which can select one of operating modes in FES for general paralysis patients. As spiral injury by traffic accident, industrial disaster, or stroke has been increased, the development of FES(Functional Electrical Stimulator) system is urgent to prevent paralysis and atrophy, and to assist the patients walking. For these patients we developed FES system(1). To operate this system one of several operating modes must be selected. As this can not be done by general paralysis patients, an attempt has been tried in this study to select the mode by speaker recognition system. RSC-300 of sensory co. has been chosen as a speaker recognition chip, and PIC16F84 is adapted to interface RSC-300 and FES system. 본 논문은 전신마비환자를 위한 FES(Functional Electrical Stimulator) 시스템 모드 변환 중의 하나를 선택할 수 있게 하는 화자 인식 시스템을 개발하고자 한다. 교통사고나 산업재해로 인한 마비환자가 늘어나고 있는 현대사회에서 환자의 운동 보조를 위해서 또는 운동 능력의 회복을 위하여 FES 시스템에 대한 연구가 늘어나고 있다. FES의 동작은 휴지, 운동, 치료 등 몇 개의 모드를 선택해야 하는데, 사지마비환자의 경우에는 키패드 조작이 불가능하므로 가장 일반적이고 자연스러운 언어로 이들 모드를 선택하고자 한다. 화자 인식 소자로는 Sensory(주)의 RSC-300을 사용하였고, FES 시스템과 RSC-300의 인터페이스는 PIC16F84마이크로 콘트롤러를 사용하였다.

Even though Hangeul is an excellent character, it has many serious problems on the machanization of chacter, on the utilization of computer, on the form of character, on the dynamics of reading, on the speed of reading, and on the recognition of word patterns etc. In this paper those problems are studied, and the adaption of Roman character is proposed as a settlement to those problems.
