Abstract: Due to the wide applications of DPWM (Digital Pulse Width Modulation) /DPFM (Digital Pulse Frequency Modulation) in the industry, a 4-bit Dual Mode (PWM/PFM) Digital Pulse Modulation (DMDPM) ...

Abstract: This paper presents an innovative prototype of a single-phase Class-E direct ac-ac converter, which achieves direct ac-ac power conversion without requiring mains polarity or phase detection ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...
