a variable frequency phase shift (VFPS) modulation is proposed without adding extra auxiliary circuit. The single-stage power conversion structure includes a dc side full bridge inverter and an ac ...

Auditory stimuli contained one of three random masking bands in the stimulus envelope, at various proximities in modulation frequency to the 4 Hz target, or an unmasked reference condition. During EEG ...

Each spectrum was obtained using a 4 G modulation amplitude, 100 kHZ modulation frequency, 10.24 ns time constant, and 20.48 ms conversion time at an attenuation of 30 dB. Each spectrum was centered ...

As is well known, modulation frequency is directly related to the penetration depth. Therefore, by controlling the frequency of matched filtering, FM-PCT can create tomographic images at various ...
