IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an ...

It turns out however that the resulting frequency response produced by this method of time domain averaging is very sensitive to even minor time domain differences in the impulse wave shapes.

International coordination, notification and recording procedures for space systems and earth stations and examination of frequency assignment notices submitted by Administrations (Membership) for ...

The properties of any harmonic bath bilinearly coupled to the system are fully captured (25) by the bath spectral density (SD) defined in the frequency domain as In this study, we reexamine this ...

First, time-domain and frequency-domain features are extracted via long short-term memory (LSTM) and convolutional neural network (CNN) models, respectively. Second, a novel functional connectivity ...

Abstract: To alleviate the computational challenges of reverse time migration (RTM) in the frequency domain, this article constructs preconditioners based on the deep learning (DL) algorithm to ...

Many of these workarounds are based on signal processing. Technologies like frequency shift keying (FSK) and multiplexing are becoming more common underwater. Some research groups have focused ...
