In this report, we describe the structure of a virtual laboratory designed for the computer-aided education. The virtual laboratory has the same environment as a real laboratory and is programmed with the object-oriented language C++. In a circuit modeling mode, we can put icons of various instruments (such as delays, multipliers, adders, function generators, oscilloscopes and frequency analyzers) on a workbench window and connect each instrument with lines by using a mouse and a cursor. The sub-circuit can be moved and deleted. In an execution mode, the integrity of the circuit is checked and a control panel is shown. The execution sequence is automatically resolved before running. When we press the icon button of a function generator, a setting window is opened. The output frequency, amplitude and wave form are easily set using dials and buttons in the setting window. The time wave and the frequency spectrum at arbitrary points in the circuit are displayed in the corresponding observation windows of oscilloscopes and frequency analyzers. The execution speed can be continuously varied in order to match the comprehension level of the students.
