An approach to integrated mixed-mode simulation is described in which the popular SPICE circuit simulator is extended to analyze digital circuits at the gate, functional or behavioral levels. The analogue-to-digital conversion is provided by (multilevel) parameterized “thresholders” which assign digital signals to subranges of voltages determined by a set of voltage thresholds. The digitalto-an...

The paper starts by describing the role of simulation and role play in education and training. A variety of examples, such as flight simulation, medical simulation, military personnel and stress, simulation in computer science education. The core definition of simulation is that it allows students to explore a problem area in a safe and controlled environment. We contrast different approaches, ...

Visualization has many meanings. In the 1980s, it indicated the process of visualizing large sets of spatial data, known as scientific visualization. Later on, the domain of visualization was expanded to abstract information, after Robertson, Card, and Mackinlav defined the concept of information visualization. In this context, visualization is a process of transforming information into a visua...

This paper presents the digital data compression of multimedia transmission system. Digital audio compression is a scheme, which allows efficient storage and transmission of audio data. The main objective of this research is to show the program in MATLAB for Moving Pictures Expert Group (MPEG-1) audio encoder and decoder for layer-1, which will be analyzed in future on Digital Signal Processing...

A machine-independent examination of the associated programming problem i s conducted and illustrated by means of a n example. Finally, the nature and application of simulation languages are noted. By system, we have in mind the meaning accorded by Webster, " a set of objects united by some form of regular interaction or interdependence. " Change in a system is regarded as change in the propert...

The paper researched and presented a virtual simulation system based on a full-digital lunar terrain, integrated with kinematics and dynamics module as well as autonomous navigation simulation module. The system simulation models are established. Enabling technologies such as digital lunar surface module, kinematics and dynamics simulation, Autonomous navigation are investigated. A prototype sy...
