Time domain antenna pattern measurements
… measurements can be made in the frequency domain, and the Fourier transform can be used to relate the frequency-domain measurements to the antenna's time-domain response. The interference then can be removed with a time-domain gate, and transformed back into the frequency domain to yield …

Time Domain Spectroscopy of Graphene
… corrections to the band structure for different times after carrier excitation. Lastly, I will describe measurements that determine the extent of electron-electron correlations in graphene fragments. By measuring the energy of the two photon state and comparing it the lowest energy one photon …

Time domain segmentation of speech signals
… rather than categorize fixed segments of time. Another goal is to produce a scheme that is applicable to real-time speech recognition. As such, the use of training data and prior knowledge of the input is avoided. To reduce computational overhead, frequency domain parameters are not used …

Time domain classification of transient RFI
… become more prominent as a result. At the same time, the prevalence of RFI-generating devices has increased as new technologies have been adopted by society. Many approaches have been developed for mitigating RFI, which are typically used in concert. New telescope arrays are often built far from …

Circuits for time-domain signal processing
… that typically operate in voltage/current domains. In this dissertation, circuits for processing the signal in the time-domain are explored where faster MOS transistors with improved timing accuracy are used to implement high precision scalable analog functions with lower power consumption. …

Calibration of time domain network analyzers
A calibration technique for time domain reflectometry and transmission (TDR and TDT) measurement system as applied to network analysis is presented. The calibration corrects for the errors caused by the response of the measurement system. A complete physically-based model has been established for …

Time-domain terahertz magneto-spectroscopy of semiconductors
… In this dissertation research I have developed a time-domain THz magneto-spectroscopy system to investigate various THz magnetic excitations in semiconductors, including a high-mobility two-dimensional electron gas (2DEG) in a GaAs quantum well and lightly-doped InSb. In the 2DEG, I have observed …

Time-domain concatenative text-to-speech synthesis.
A concatenation framework for time-domain concatenative speech synthesis (TDCSS) is presented and evaluated. In this framework, speech segments are extracted from CV, VC, CVC and CC waveforms, and abutted. Speech rhythm is controlled via a single duration parameter, which specifies the initial …

Techniques for discrete, time domain system identification
… system identification techniques for discrete, time domain, linear, MIMO, heavily damped modal systems from input/output sequences have been developed and simulated. This will facilitate a better understanding of the possible errors in the estimated model and lead to a more accurate compensator …

Maximum likelihood time-domain beamforming using simulated annealing
… is used to estimate the source bearings and time series. Simulated annealing is used to implement the resulting time-domain beamformer. Broadband signals in spatially correlated noise are treated. Previous time-domain beamformers did not consider the correlation between random noise, and they …

Speech/Music Discrimination: Novel Features in Time Domain
… to discriminate between speech and music in the time domain for the purpose of data retrieval. The study used speech and music data that were recorded in standard anechoic chambers and sampled at 44.1 kHz. Two types of new features were found and thoroughly examined: the Ratio of Silent Frames …

Time-domain developments in the singularity expansion method
… of the best properties produced by SOT (low flow time) and SLACK (low tardiness). It should be noted that even though such a system could be viewed as complex and expensive,it is not. Computational requirement will be slightly increased, but no more data is required than is expected for a typical …

Time domain metrology for dielectric spectroscopy of particulates
… of soil samples using measurements in the time domain were studied. A number of algorithms for inverting the measured data to obtain epsilon were investigated and three different types of sampling devices were examined. The investigation examined the positive and negative aspects of three …

Steady-State Time-Domain Analysis of LLCL Resonant Converter
… of a series resonant converter, frequency domain modelling (FDM) is usually sufficient due to the limited modes of operation. However, for a three or more element resonant tank, multiple modes of operation arises due to which FDM is restricted for analysis for operation below resonant …
