The UTC Graduate School is pleased to announce that James Carpenter will present Master's research titled, Analysis of Single Event Transients in Arbitrary Waveforms using Statistical Window Analysis on 06/23/2023 at 1pm in ECS 231. Everyone is invited to attend. 


Chair: Daniel Loveless

Window or taper functions are commonly used in data processing to detect transient events or for time-averaging of frequency spectra. A generalized window function is demonstrated us- ing the Ionizing Radiation Effects Spectroscopy (IRES) technique to enhance the measurement of transient anomalies within arbitrary waveforms. The IRES filter is used to convolve time data with a sliding window consisting of a moment- generating function. The resulting time-dependent sta- tistical moments can be used to eliminate any steady-state signatures, including noise, and extract transient behaviors. The IRES filter analyzes data from heavy-ion exposures of commercial off- the-shelf (COTS) operational amplifiers, laser-induced transients in Complemntary Metal-Oxide- Semiconductor (CMOS) phase-locked loops, and simulated transients in digital and analog circuits. The performance of the IRES filter in noisy environments shows that transients can be measured with higher fidelity than standard amplitude thresholding. This statistical window analysis tech- nique may remove the need for complex triggering mechanisms on instrumentation and does not require a-prior knowledge of transient characteristics. Potential applications of IRES include real- time measurement, in-situ data analysis, and machine learning.
