- A large modulation index is needed for practical reasons.
- This is explained by the absence of change in the Attention Modulation Index ( AMI ).
- Sometimes modulation index h < 0.3 rad is considered as Narrowband FM otherwise Wideband FM.
- In this simple case " M " is identical to the modulation index, discussed below.
- In FMS, the light is modulated at a much higher frequency but with a lower modulation index.
- Alt = Graphs illustrating how signal intelligibility increases with modulation index, but only up to 100 % using standard AM.
- This is the smallest FSK modulation index that can be chosen such that the waveforms for 0 and 1 are orthogonal.
- However it is possible to talk about a modulation index exceeding 100 %, without introducing distortion, in the case of double-sideband reduced-carrier transmission.
- This is why Apollo uses a low modulation index : to leave a strong carrier that can be used for highly accurate velocity tracking by measurement of its Doppler shift.
- For a sine wave modulation, the modulation index is seen to be the ratio of the peak frequency deviation of the carrier wave to the frequency of the modulating sine wave.
- In all such cases the term " modulation index " loses its value as it refers to the ratio of the modulation amplitude to a rather small ( or zero ) remaining carrier amplitude.
- The high-frequency signal components are emphasized to produce a more equal modulation index for the transmitted frequency spectrum, and therefore a better signal-to-noise ratio for the entire frequency range.
- Thus double-sideband transmission is generally " not " referred to as " AM " even though it generates an identical RF waveform as standard AM as long as the modulation index is below 100 %.
- However, sleep deprivation does not affect the attention modulation index of the PPA . With this information, researchers have concluded that the psychophysiological interaction ( PPI ) is more involved in selective attention than the IPS and PPA.
- With a tone-modulated FM wave, if the modulation frequency is held constant and the modulation index is increased, the ( non-negligible ) bandwidth of the FM signal increases but the spacing between spectra remains the same; some spectral components decrease in strength as others increase.
- When the AC output is at frequency fc with its amplitude at v c, and the triangular carrier signal is at frequency f ? with its amplitude at v ?, the PWM becomes a special sinusoidal case of the carrier based PWM . This case is dubbed sinusoidal pulse-width modulation ( SPWM ) . For this, the modulation index, or amplitude-modulation ratio, is defined as "'v c / v " } } " '.
