[Expand Summary]
The integrate-and-dump detector is fundamental to coherent detection, the optimal receiver technique that minimizes bit error rate (BER) for a given signal-to-noise ratio Eb/No. In this project develop a pulse amplitude (PAM) transmitter based on a transmit filter to map a bitstream onto a signaling waveform (rectangular and Manchester pulse shapes), an additive white Gaussian noise (AWGN) channel, and a receiver that implements integrate-and-dump detection. All waveforms throughout the signal processing chain are presented as a stacked chart indicator with a speed control to permit generated waveforms to be studied slowly (i.e., the integrator output ramping up or down) or quickly to process long message bitstreams. Visualizing the critical system signals as waveforms facilitates exploration of the effects of specific values of BER and Eb/No, and promotes deeper understanding of coherent detection.

[Expand Summary]
"Musical Signal Processing with LabVIEW," a multimedia educational resource for students and faculty, augments traditional DSP courses and supports dedicated courses in music synthesis and audio signal processing. Each of the learning modules blends video, text, sound clips, and LabVIEW virtual instruments (VIs) into explanation of theory and concepts, demonstration of LabVIEW implementation techniques to transform theory into working systems, and hands-on guided project activities. Screencasts -- videos captured directly from the computer screen with audio narration and a hallmark of this resource -- use a mixture of hand-drawn text, animations, and video of the LabVIEW tool in operation to provide a visually rich learning environment. *** Unlike other collections that contain sub-sets of modules from this course, this collection contains all modules. ***
