today's rapid development in mobile technology, wireless devices such
as the Apple iPhone, the iPod touch and the iPad have become popular
platforms for education. Their advanced multi-touch interface and
improved processing power can also be exploited for engineering
and STEM education demonstrations. In addition, as normal computing
moves from the desktop to handhelds, the potential to encourage
students into science and engineering is very real. i-JDSP
is an interactive iPhone/iPad-based digital signal processing (DSP)
laboratory developed at Arizona State University based on the award winning
online laboratory J-DSP. The
i-JDSP iPad/iPhone environment (soon-to-be a formal iPad/iPhone
application) is implemented in Objective-C and C as a native Cocoa
Touch application that can be run on any iOS device. i-JDSP
offers basic signal processing simulation functions such as FFT,
filtering, frequency response, PZ plot and PZ placement on the new
compact and convenient
iPhone/iPad graphical user interface (GUI) and provides a very
compelling multi-touch programming experience. It also incorporates
MIDI, DTMF, sound recorder and playback functionalities. All
simulations can be
visually established by forming interactive block diagrams through
multi-touch and drag-and-drop. The iPad/iPhone platform is very
attractive and we expect that this new environment will expand the
community of student and faculty users. The software will be
disseminated in the DSP and Signals and
Systems classes at ASU. We will create and monitor a
community of student users and we will also develop specific online
laboratories and exercises based on this platform.
