AM是 "振幅调制(amplitude modulation)"的意思。 而信号的振幅基本上是指声音的音量。 振幅调制是指这个音量被调制:音量跟随另一个信号变化。 所以对于AM合成,你实际上需要2个振荡器。一个是声源,提供你能听到的声音,它被称为载波(carrier),另一个是控制第一个振荡器的音量旋钮的,它被称为调制波(modulator)。

Friedel's theory for the amplitude-dependent damping produced by the thermally activated unpinning of dislocations is extended to sinusoidal stresses. It is shown how to apply the theoretical expressions to experimental data and some numerical analyses are given of results obtained in a high-purity ...
摘要: Push-pull modulation of a two contact, uniform DFB laser enables AM modulation bandwidths well beyond the conventional electron-photon resonance limit for single contact devices. A small signal analytic theory for this AM response is given....
Our understanding of the Madden-Julian Oscillation (MJO) and other tropical motion systems has significantly improved in recent years. This article reviews
This is a core theme in the area of amplitude/modulation equations [96]. Recently, efforts have begun to extend geometric singular perturbation theory also to PDEs formulated on unbounded domains [97]. While inertial and slow manifold reductions aim to describe the dynamics of a system in a ...
These are then applied to a study of the transmission, reception and detection of frequency modulated waves. A comparison with amplitude modulation is made and quantitative formulas are developed for comparing the noise-to-signal power ratio in the two modes of modulation....
We discuss the performance of an atomic force microscope (AFM) operated in the amplitude modulation mode under a self-excitation signal, known as quality factor control(Qcontrol). By using the point-mass description of the AFM, we provide a complete description ofQcontrol in tapping mode AFM....
A one-to-one correspondence between the evolution of the amplitude and that of the phase is verified. The mean flow is also found to undergo the same periodic modulation. These results are used to derive coupled nonlinear equations describing the amplitude oscillation, vortex nutation, and ...
