Bilateral collicular interaction: Modulation of auditory signal processing in frequency domain
Neuroscience, 2013In the ascending auditory pathway, the inferior colliculus (IC) receives and integrates excitatory and inhibitory inputs from a variety of lower auditory nuclei, intrinsic projections within the IC, contralateral IC through the commissure of the IC and the auditory cortex.

A frequency-time domain signal processing system.
Medical instrumentation, 1980A digital signal processing system for time series analysis with two modes of usage--the first a rapid, hands-on exploratory method, and the second an automatic, printed, labeled graphic output method--is described. The system utilizes a Time Data 1923C system with integral PDP-11 minicomputer, and a console.

Medical Engineering & Physics, 2008
Two methods for analyzing intracranial pressure (ICP) waveforms were compared. The frequency domain (FD) method converts the signal from the time domain to the frequency domain by a fast Fourier transform (FFT), while the time domain (TD) method calculates peak-to-peak value of the pulse waveform directly from the time samples.

Mobile teletext reception using signal processing in frequency domain
IEEE Transactions on Broadcasting, 1990An experimental study of mobile teletext reception is described. Teletext in Japan is a broadband signal with 5.73 Mb/s; therefore, multipath interference is a serious problem in mobile reception, and it is impossible to obtain the teletext correctly by conventional methods.

A frequency-domain beamforming algorithm for wideband, coherent signal processing
The Journal of the Acoustical Society of America, 1984Coherent detection processors for sonar (e.g., matched filters for active systems) require continuous time series as input and have conventionally been coupled to delay-and-sum time-domain beamformers. As an alternative, we have extended the FFT beamforming technique to be functionally equivalent to a time-domain beamformer. The procedure utilizes the ‘

Processing methods in frequency domain for bubble laser scattering signals
SPIE Proceedings, 2009For the detection of the bubble-laser-scattering property, it is the key to improve the signal to noise ratio. The various noises in the bubble-laser-scattering signal, the background light, power frequency of 50Hz, radio frequency noise and inherent noise within the electronic system, are analyzed in detailed.

PREDICTION AND SIGNAL EXTRACTION OF STRONGLY DEPENDENT PROCESSES IN THE FREQUENCY DOMAIN [PDF]
Econometric Theory, 2002 We frequently observe that one of the aims of time series analysts is to predict future values of the data. For weakly dependent data, when the model is known up to a finite set of parameters, its statistical properties are well documented and exhaustively examined. However, if the model was misspecified, the predictors would no longer be correct.

Modern Spectral Estimation for Signal Processing in the Frequency Domain
Spectroscopy Letters, 2000Abstract Modern power spectral estimation technique was applied to the signal analysis of inductively coupled plasma atomic emission spectrometry (ICP-AES) in the present work. Two methods, Levinson-Durbin and Burg methods, were used to calculate auto-regression (AR) model parameters and the comparison was made.
