In the last few years there has been a tremendous increase in the number of Pascal courses taught at various levels in schools and universities. Also with the advances made in electronics it is possible today for the majority of people to own or have access to a microcomputer which invariably runs BASIC and Pascal. A number of Pascal implementations exist and in the last two years a new Pascal specification has emerged. This specification has now been accepted as the British Standard BS6192 (1982). This standard also forms the technical content of the proposed International Standard IS07185. In addition to a separate knowledge of electronic engineering and programming a marriage of engineering and computer science is required. The present method of teaching Pascal in the first year of electronic engineering courses is wasteful. Little, if any, benefit is derived from a course that only teaches Pascal and its use with abstract examples. What is required is continued practice in the use of Pascal to solve meaningful problems in the student's chosen discipline. The purpose of this book is to make the use of standard Pascal (BS6192) as natural a tool in solving engineering problems as possible. In order to achieve this aim, only problems in or related to electrical and elec tronic engineering are considered in this book. The many worked examples are of various degrees of difficulty ranging from a simple example to bias a transistor to programs that analyse passive RLC networks or synthesise active circuits.
