The generation of multitone signals for use in built-in self-test (BIST) mixed circuits is challenging due to requirements such as resource usage and testing time. Generating offline the complete waveform and storing it for posterior playback is not

Grounding systems play an important role in electrical substations. They prevent grounding potential rise (GPR) during current fault events. GPR can cause the known step or touch voltages that can hurt people around the substations. Over time, ground

In this paper we investigate the use of the Support Vector Machine (SVM) approach to develop simple and efficient VLSI architectures for real-time digital modulation classification. Such simplicity and efficiency arise from the adoption of a front en

This paper presents VLSI architectures to perform Digital Modulation Classification based on Support Vector Machines. In order to obtain suitably small circuitry, the designed architectures use a recently proposed front end that is based on histogram
