Webresponse is TSP (time stretched pulse [4]), which is also called ‘swept-sine’. Its frequency is swept linearly as time increases. On the contrary, the frequency of Log-TSP is swept logarithmically (Log-frequency is proportional to time). Figures 2(a) and 2(b) show the spectrograms of TSP and Log-TSP, respectively. WebTime stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed.Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed … shankman leone p.a

"Webpulse. The generated NIR pulses are coupled into a single-mode fiber with a coupling efficiency of 0.65 and optically amplified with an Er-doped fiber amplifier (EDFA) . Subsequently, they are temporally stretched by dispersion -compensating fibers (DCF) with a total length of 10, 30, or 60 km. The DCF ’s dispersion parameter is -0.2 ns/nm/km.

The time-stretch processor, which is generally an optical frontend, stretches the signal in time. It also divides the signal into multiple segments using a filter, for example, a wavelength division multiplexing (WDM) filter, to ensure that the stretched replica of the original analog signal segments do not overlap each other in time after stretching. The time-stretched and slowed down signal seg…
