This paper proposes an alternative configuration for digitally controlled parallel connected DC–DC power converters. Unlike conventional scheme which uses only one digital controller to control all of the n parallel connected power converters, the proposed scheme employs n digital controllers for n paralleled power converters. This arrangement prevents single controller breakdown from faulting ...

The optical gain-depletion-induced mode-locking dynamics of a semiconductor optical-amplifier-based fiber ring laser (SOAFL) backward injected by a purely sinusoidally modulated or digitally encoded distributedfeedback laser diode are theoretically and experimentally demonstrated. The effect of gain depletion and waveform on the mode-locked pulse width, pulse shape, and power of the SOAFL are i...

A simple technique is presented to realize a digitally programmable voltage mode quadrature oscillator using second generation current conveyors. Firstly, the current conveyors based tunable quadrature oscillator is realised. A digital block is introduced in the realized tunable quadrature oscillator so that the oscillator can be controlled digitally. The realized Digitally Programmable Quadrat...

Lawful access—the legal regime that authorizes various methods used by law enforcement to intercept, search, or seize information for investigatory purposes—has been subject much debate in Canada. However, those debates need a new solution space the digital age. This must be able incorporate technological solutions minimizing rights infringements and provide forms of accountability safeguards a...
