Synaptic transistors with aluminum oxide dielectrics enabling full audio frequency range signal processing

Specific signal processing for high frequency range in Audio - Magnetotelluric

The usual methodology used in magnetotelluric signal processing (MT) has been studied and applied to the case of audio-magnetotellourics (AMT). The results obtained have proved not to be good enough in order to obtain a good subsurface resistivity model. Therefore, some changes have been made to the methodology of signal processing so that it suits audio-magnetotellurics. These changes have app...

Zirconium oxide-aluminum oxide nanolaminate gate dielectrics for amorphous oxide semiconductor thin-film transistors

The dielectric properties of ZrO2–Al2O3 nanolaminates, deposited via atomic layer deposition, and their impact on the performance and stability of indium gallium zinc oxide and zinc tin oxide amorphous oxide semiconductor thin-film transistors TFTs are investigated. It is found that nanolaminate dielectrics can combine the advantages of constituent dielectrics and produce TFTs with improved per...

High Dynamic Range Audio Applications For Digital Signal Processing

Application of digital signal processing to audio is often limited by available converter technology and recorder datawidth to processes with controlled dynamic range. In digital mixing consoles some analogue gain control is normally required to achieve adequate performance for the input channel ADCs and digital multi-track recorders. This paper examines such dynamic range bottlenecks and deriv...

An Amplitude- and Frequency-modulation Vocoder for Audio Signal Processing

The decomposition of audio signals into perceptually meaningful modulation components is highly desirable for the development of new audio effects on the one hand and as a building block for future efficient audio compression algorithms on the other hand. In the past, there has always been a distinction between parametric coding methods and waveform coding: While waveform coding methods scale e...
