Amplitude modulation (AM) is a modulation technique in which the amplitude of a high frequency sine wave (usually at a radio frequency) is varied in direct proportion to that of a modulating signal.The modulating signal carries the required information and often consists of audio data,as in ...

How to minimize the amplitude modulation in the phase modulated light modulator and phase modulated light modulatorThe invention relates to a phase-modulating light modulator and to a method for ensuring a minimal amplitude modulation in phase-modulating light modulators, wherein the phase-modulating ...
The invention relates to methods which make it possible to modulate the amplitude of a carrier which is intended, in particular, to interrogate a label of operating without contact.elle is to supply the output transistor (301) of the emitter of the interrogation signal with the aid of an impa...
For high-power decoupling the method results in very good decoupling provided that certain unfavorable recoupling conditions, imposed by specific ratios of the amplitude modulation frequency and the MAS frequency, are avoided. For low-power decoupling, the method leads to acceptable decoupling when the...
, we find strong supporting evidence that the small-scale structures are subject to a high degree of amplitude modulation seemingly originating from the much larger scales that inhabit the log region. An analysis of the Reynolds number dependence reveals that the amplitude modulation effect becomes ...
ACTH secretory bursts were discrete punctuated events arising without tonic interpulse secretion and had a half-duration (duration at half-maximal amplitude) of 19 +/- 2 min. The estimated half-life of endogenous ACTH was 15 +/- 1.2 min, and its daily production rate was 0.96 +/- 0.16 ...
In this article, I will explain pulse amplitude modulation and demodulation method in detail using suitable waveform and frequency spectrum. This article is easy to understand, clear and with all the information. Suitable for engineering and diploma ...
Modulation Depth Determines the maximum variation in amplitude that occurs. For example, you can alter the amplitude of a chorused voice so that it is 5 dB louder or quieter than the original. At extremely high settings, the sound may cut in and out, creating an objectionable warble. At ...
