Interactive Coding of Visual Spatial Frequency and Auditory Amplitude-Modulation Rate
Spatial frequency is a fundamental visual feature coded in primary visual cortex, relevant for perceiving textures, objects, hierarchical structures, and scenes, as well as for directing attention and eye movements. Temporal amplitude-modulation (AM) rate is a fundamental auditory feature coded in primary auditory cortex, relevant for perceiving auditory objects, scenes, and speech. Spatial fre...
متن کاملAuditory-Visual Speech Recognition with Amplitude and Frequency Modulations
A recent study by Zeng et al (2005) [PNAS, 102, 2293-2298] demonstrated the importance of FM cues for auditory speech identification in a competing noise environment. The current speech identification study investigated this finding for both an Auditory Only (AO) and an Auditory-Visual (AV) speech in noise identification task. The results demonstrated an FM advantage (compared to AM only) for b...
متن کاملAmplitude and Frequency/Phase Modulation
I always had difficulties in understanding frequency modulation (FM) and its frequency spectrum. Even for the pure tone modulation, the FM spectrum consists of an infinite number of sidebands whose signs change from one sideband to the next one and whose amplitudes are given by the horrible Bessel functions. . . I work for Zurich Instruments, a Swiss maker of lock-in amplifiers and it has becom...
متن کاملSpatial horizons in amplitude and frequency modulation atomic force microscopy.
In dynamic atomic force microscopy (AFM) the cantilever is vibrated and its dynamics are monitored to probe the sample with nanoscale and atomic resolution. Amplitude and frequency modulation atomic force microscopy (AM-AFM and FM-AFM) have established themselves as the most powerful methods in the field. Nevertheless, it is still debatable whether one or the other technique is preferred in a g...
متن کاملAn 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...
