Signals and Systems Simulation for iPad

Description of the Project

The project aim is to create an iPad simulation for the Signals and Systems courses. These projects have three submenus.

• Visualizations
• Explorations
• Drill Problems

In Visualization part, program shows the some examples of the signals and convolutions. User can choose the filter and signal type for the simulation of convolution to understand the process for the systems.

In Explorations part, program record the voice from outside and use these signals as an input for filters. Filters are low-pass filter and high pass filter. User listen these output records after the filtering process.

In Drill Problems, program shows some of the examples about the Signals and Systems courses.
