Expressions of power spectrum forSS OOK modulation are presented in Figure 2 for the case of a rectangular envelope. Figure 2: One-sided power spectrum of coherent and noncoherent OOKwith a ...
The diode detector provides the amplitude or envelope of the signal (s) within that wavelength. A high impedance or highly sensitive ear piece converts this envelope to an audible signal that you ...
Whether this envelope approximation technique yields sufficiently accurate results is for the user to decide. Its accuracy may be below the requirements of most AM (amplitude modulation) detection ...
The envelope detector comprises a common-source amplifier that's nominally biased to operate in Class B mode. To increase this stage's gain, you apply a small amount of bias current to make it operate ...

But when an impact occurs, its amplitude is modulated; in other words, it rings more loudly. (On a bearing, a roller hitting a fault acts as a striking gong; the bearing acts as the bell.) ...
