Waveform Shaping of Output Pulse of Pulse Forming Network for Klystrom Modulator Using a Waveform Compensation Circuit

Waveform Characterization for Spectral Line-by Line Pulse Shaping

We have developd new techniques that enable characterization of ultrafast optical waveforms generated via spectral line-by-line pulse shaping under the Optical Arbitrary Waveform Generation (O-AWG) program. Our approaches simultaneously address a number of challenging requirements not met by existing waveform measurement methods, including high waveform complexity, high spectral resolution, and...

Design of Monophasic Spike-Exponential Waveform for Functional Electrical Stimulator Based on Pulse Width Modulation

The Functional Electrical Stimulator design using monophasic spike-exponential waveform was proposed and described in this study. The monophasic square waveform has benefit in generating an action potential, but it could cause side effects such as toxic caused by the electrode polarization. The square waveform signal which the frequency and pulse width could be modulated was manipulated to be t...

Improvement of Waveform Efficiency Using a Compensation Circuit

In order to improve the efficiency(usable RF to total pulse) of a klystron modulator, a system using a solidstate compensation circuit has been developed. This system remarkably improves a flat-top and flatness of the output waveform of the modulator by means of waveform synthesis. This paper presents the design and specifications of the compensation circuit and the results of a preliminary tes...
