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 ...

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 ...

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 ...

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 ...

This work presents a sweep for the modulation index in a 27-Level Asymmetric Multilevel Converter that uses the Selective Harmonic Elimination modulation technique. Different set of solutions are obtained and presented in ...

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 ...
