Alias-free digital click modulator
(Ieee-inst Electrical Electronics Engineers Inc, 2013-05)
An alias-free, discrete-time click modulator is developed in this paper. Previous approaches rely on translating the continuous-time click modulator to a discrete-time setting, although a key component in the click ...
Design of a Multiport Microwave Modulator for Dynamic Polarization Reconfiguration
(Institute of Electrical and Electronics Engineers, 2019-05)
This paper presents a seven-port modulator capable of switching the polarization state of the transmitting signal. Similar to the six-port modulator, the proposed device modulates the carrier signal through the reflection ...
Low Cost Digital Module for Demonstration of Modulation Strategies in DC-to-AC Converters
(Ieee, 2017-01-01)
This paper presents the development of an educational digital module able to generate control signals considering several modulation strategies for DC-to-AC converters, single and three-phase, to achieve the integration ...

Practical evaluation of different modulation techniques for current-controlled voltage source inverters
(INST ENGINEERING TECHNOLOGY-IET, 1996)
The quality of the current waveform generated by a current-controlled, voltage source inverter, depends basically on three factors: (a) the switching frequency of the PWM modulator; (b) the type of current waveform being ...

Theoretical analysis and experimental results on the modulated photocarrier grating technique
(Wiley Vch Verlag, 2010-01)
We present a complete theoretical analysis of the modulated photocarrier grating method (MPG). Our calculations show that the response of the sample will be not only a photocurrent modulated with the frequency f of the ...
