This course is an introduction and survey of signal processing for beginner and intermediate levels. The course will introduce basic math concepts fundamental to and applications of signal processing. The course will explore properties of signals and systems including spectral estimation, detection and information theory.
In this workshop, we dive into our newly-introduced RFML toolkit, TorchSig. We step through the installation process, dataset generation examples, data augmentation pipelines, and example training scripts using the Sig53 dataset as well as fine-tuning to over custom datasets. Please join us for this code walkthrough and bring any questions on the toolkit’s capabilities and how it can be...
Dan Romanchik KB6NU from ARDC is putting on a Tech class review Q&A prior to the Amateur Radio exams. Feel free to use this room for individual studying, or to get help from Dan. It is highly recommended to start studying prior to GRCon, Dan has created a series of free Technician Class study guides which can be found here https://www.kb6nu.com/study-guides/
This presentation gives an overview of mathematical concepts used for signal representation in communication systems. Topics covered include: baseband/bandpass signals; signal duration/bandwidth and the time-bandwidth product; representations of bandpass signals in terms of baseband equivalents (I/Q components and envelope/phase); signal mixing and the superheterodyne principle; sampling and...
