The intent of this study is to investigate the history and typology of campus from a particular point of view-the relationship of campus to its context. As a logical ground for this study, the ideal roles of a modern university are defined, which include the social role. Five types of campuses from various periods and their formal implications are identified, stressing the degree of interaction the campus had with the outside world. This analytic approach is to understand the underlying ideas of a campus layout and the trends of its development. It also enables us to discover new dimensions of campus planning and design, that may be highly relevant to the recent and future needs of the campus planning process.

Successive approximation type A/D converter has been designed based on microprogram techniques. The circuitry have been implemented with low cost D/A converter, D-latch and Mos EPROM. As an experimental result, A/D conversion time as high as 714 nanoseconds per bit could be achieved.

In most cases of the analysis of analog modulated signals, phasor interpretation is required to calculate the frequency spectrum and therefore its bandwidth. In this paper, the comprehensive modulated signals including Monos and Compatible AM Stereos are analized to get the phasor diagram and therefore to locate the sidebands without mathematical complexity as much as possible. At first, a series of simple modulated signals are considered and then these results are applied to obtain phasors of other sophisticated modulation systems easily. Then the practical AM compatible stereo systems including the newly proposed one are introduced and simulated for their time domain operations on a digital computer.
