Application Software of the Future-Filter Design with Gem

As the use of computers in engineering design as well as other areas increases, it becomes more imperative that the application software used be as simple, convenient, and powerful as possible. The engineer is not interested in the internal workings of the computer or its operating system. It is the design itself that takes precedence. The filter design package developed for this project, known as FILTER, is such an application. With FILTER, coupled with the Digital Research Graphics Environment Manager, the engineer is led through the analog and digital filter design phase on a personal computer · with carefully designed interactive computer graphics requiring little or no computer knowledge.
