Oscilloscope v. 2.51

Oscilloscope for Windows is a Windows application that converts your PC into a powerful dual-trace oscilloscope. Oscilloscope uses your PC's sound card as an Analog-to-Digital Converter (ADC) to digitize any input waveform (speech, music, electric signal, etc.) and then presents it on the monitor in real time, allowing the user to control the display in the same way as on a conventional "standalone" scope, for example change gain, time base or plot Lissajous patterns.

Edison Version 3

Edison Version 3 is a unique new learning environment for electricity and electronics. Teachers and students can use multimedia screens, virtual instruments, sound, and animation to create, test, and safely repair circuits. Lifelike 3-D components will captivate the students as they build circuits and simultaneously see the corresponding circuit schematic. Edison also comes with over 100 experiments and problems that teachers and students can use immediately.

Select realistic batteries, resistors, diodes, LEDs, transistors, logic gates, flip-flops, and even integrated circuits all easily available on the shelves of your multimedia lab. Drag them onto your "breadboard" and wire them together with your mouse. Your circuit begins working immediately so you can test and troubleshoot it with virtual instruments. In addition, Edison automatically prepares a standard schematic diagram and displays it simultaneously.
