With loudspeakers, an important parameter is the frequency at which their cones resonate. This clever Arduino-based tester ...
Abstract: The backward wave oscillator (BWO) is an important vacuum electron source that utilizes backward waves to interact with electron beam, resulting in high-frequency self-excited oscillations.
Abstract: This paper presents the design and implementation of an ultra-low phase noise 100MHz crystal oscillator, along with the development and simplification of its noise theory. Specific circuit ...
