调制指数 Modulation Index指的就是公式中d/f_m*sin(2πf_mt)的最大值,这里也就是 d/f_m=> Modulation Index 最大频偏 peak frequency deviation就对应 d d => ∆f ⚠️注意,最大频偏∆f 其实和调制信号的频率没有关系,而在 ∆f 保持不变的情况下,Modulation Index 和调制信号的频率f_m成反...

To solve this problem, a meshing frequency modulation index (index MFM )-based kurtogram utilizing a particular gearbox related phenomenon is proposed. The underlying mechanism is such that although the gear meshing-related spectral components are always more prominent in relatively higher-frequency band...

Modulation index estimation is important in the demodulation and recognition of Angle Modulation (AM) signals which include Frequency Modulation (FM) and Phase Modulation (PM) signals. In this paper, we firstly analyzed the AM signals with baseband modulation types, such as monotone, PSK, FSK, ...
The distribution and amplitudes of the frequencies present are seen to depend upon the value of an absolute parameter, the "frequency modulation index," equal to the ratio of the maximum frequency deviation to the imposed modulating frequency. The overall width of the band occupied is found to ...

How can I calculate the modulation index for a digital frequency modulated signal (2FSK, 2GFSK, 4FSK, 4GFSK)? Answer The general formula for the modulation index is the following: where H is the modulation index, M is the modulation alphabet size (e.g. M=2 for 2FSK / 2GFSK)...
