Rolloff is the amount of attenuation that is applied to sounds, based on the listener's distance from the sound source. DirectSound can ignore rolloff, exaggerate it, or give it the same effect as in the real world, depending on a global parameter called the rolloff factor....

further comprising a demodulator; wherein the modulator has a first root-raised cosine filter having a first roll-off factor and each receiver has a second root-raised cosine filter having a second roll-off factor, the first roll-off factor being smaller than the second roll-off factor.Ernest...
We evaluate the dependence of system performance on the roll-off factor, α, of a Nyquist pulse in a single-channel 1.28 Tbit/s-525 km transmission both experimentally and analytically. Low α values are preferable in terms of spectral efficiency and tolerance to chromatic dispersion and polariza...
In this work, we explore the impact of the optical filter roll-off factor on Nyquist pulses for a three-line comb with a frequency spacing of 8.4 GHz using a wideband on-chip silicon Mach-Zehnder modulator. Furthermore, we characterize the integrated modulator and compare the sinc-shaped ...
