Detection of combined frequency and amplitude modulation.
This article is concerned with the detection of mixed modulation (MM), i.e., simultaneously occurring amplitude modulation (AM) and frequency modulation (FM). In experiment 1, an adaptive two-alternative forced-choice task was used to determine thresholds for detecting AM alone. Then, thresholds for detecting FM were determined for stimuli which had a fixed amount of AM in the signal interval o...
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 کاملSpurious cross-frequency amplitude-amplitude coupling in nonstationary, nonlinear signals.
Recent studies of brain activities show that cross-frequency coupling (CFC) play an important role in memory and learning. Many measures have been proposed to investigate the CFC phenomenon, including the correlation between the amplitude envelopes of two brain waves at different frequencies - cross-frequency amplitude-amplitude coupling (AAC). In this short communication, we describe how nonst...
متن کاملCombined CELP Speech Coding and Quadrature Amplitude Modulation
In this paper, a method for optimizing the index map between the output indices of a wideband (7 kHz) CELP speech coder and the channel symbols for a power constrained channel and multilevel signaling is presented. The method is based on simulated annealing and makes use of dynamic scaling of a QAM signal constellation during the optimization procedure in order to optimize for a fixed transmitt...
