Abstract: This paper demonstrates the deployment of quadratic curve fitting (QCF) based on half-peak Brillouin gain spectrum (BGS) for fast and accurate Brillouin frequency shift (BFS) extraction. The ...
KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.
Abstract: Global Navigation Satellite System (GNSS) has a broad range of applications in both civil and military fields. However, the ubiquitous interference signals significantly disrupt the proper ...
How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...
