Signal Processing and Propagation for Aeroacoustic Sensor Networking,” Ch

Passive sensing of acoustic sources is attractive in many respects, including the relatively low signal bandwidth of sound waves, the loudness of most sources of interest, and the inherent difficulty of disguising or concealing emitted acoustic signals. The availability of inexpensive, low-power sensing and signal-processing hardware enables application of sophisticated real-time signal processing. Among th

Interactive Signals and Systems Laboratories Using Notebooks

This paper presents three interactive signal processing laboratories that use Matlab programs linked to a Microsoft Word document (a notebook ) . The active filter analysis and design, convolution and concert halls, and spectral analysis labs are designed for third-year students in a signals and systems course. These labs engage the students in the learning process by providing them with the opportunity to experiment and ask what if questions with a minimum of additional computational and documentation effort
