AcqKnowledge can be used to obtain the power spectrum of any time domain waveform. The power spectrum indicates the power of each frequency component of the source time domain waveform. The power spectrum can be used to analyze a variety of physiological signals. The ECG (rate) and EEG signals are often categorized using spectral analysis.
This application note shows how to relate power in the time domain to power in the frequency domain using very simple signals in hopes of clarifying the explanation. The FFT in AcqKnowledge allows frequency representation using linear or logarithmic scaling. All discussions and analyses for this paper are done using linear scaling.
A successful lab is one where students are fully engaged and learning the concepts—where they can achieve their goals without wasting time on equipment setup and confusing processes. Join Cindy Marolf, EdD, Nebraska Wesleyan University, as she discusses how she’s utilized the Biopac Student Lab to customize her students’ lab experience and the positive impact it has had on both her and her students. Learn about the benefits of adding a teaching solution, increasing student engagement with technology, reducing the amount of work for Professors, and options for core lessons, creating custom lessons, and scaling lessons to fit with your course curriculum.
Register NowTechnology is more interactive in a multitude of contexts, from completing tasks at work, looking for help online, to leisurely activities like news and video streaming. Understanding how to improve interaction between humans and computers can hold benefits in multiple situations. The following are recent human-computer interaction (HCI) studies. The Eyes Have It Nasser et al. […]
With new developments happening daily, it’s easy to forget to slow down and take a breath. Breathing can be as forgettable as it is crucial; the often forgettable automatic function inspires rituals in religions around the world. Studies have shown the importance of breathing not just in a spiritual sense but also in physiological health benefits. Lung functionality […]
