• waveform
  • So-called "Gabor grains" have the frequency of the waveform independent of the grain duration, whereas "wavelets" maintain an inverse relation between frequency and duration, and hence are useful in analysis and re-synthesis models. (sfu.ca)
  • human
  • The history of brain-computer interfaces (BCIs) starts with Hans Berger's discovery of the electrical activity of the human brain and the development of electroencephalography (EEG). (wikipedia.org)
  • either
  • As the temporal shape of a sound becomes elongated, whether by a small percentage or a very large amount, one's attention shifts towards the spectral components of the sound, either discrete frequency components, harmonics or inharmonics, or resonant regions and broadband textures. (sfu.ca)
  • system
  • The auditory system balances its frequency and temporal resolution in a manner that is consistent with the perception of linguistic phonemes where the simultaneous recognition of both spectral and temporal shapes plays a crucial role in rapid identification of speech. (sfu.ca)
  • The system measures the pressure pulses in an upper body peripheral artery and produces an electrical signal which represents the contours of these pulses. (google.com)
  • Next, the system separately averages the signals corresponding to the measured pulses and those corresponding to the synthesized pulses, and forms for each an 'average pulse. (google.com)
  • a computer configured to process the ultrasound data and position data to thereby determine the location of the point associated with the surface of the animal organ with respect to an on site reference coordinate system. (google.es)
  • control
  • Moreover, it is the time domain parameters involved in each model that control the bandwidth of the result, usually intended to shape the formant regions of the simulated vowels. (sfu.ca)
  • A brain-computer interface (BCI), sometimes called a neural-control interface (NCI), mind-machine interface (MMI), direct neural interface (DNI), or brain-machine interface (BMI), is a direct communication pathway between an enhanced or wired brain and an external device. (wikipedia.org)
  • The 1977 experiment Vidal described was noninvasive EEG control of a cursor-like graphical object on a computer screen. (wikipedia.org)
