Matlab self phase modulation
Web19 aug. 2024 · A self-oscillating microcantilever in a feedback loop comprised of a gain, a saturator, and an adjustable phase-shifter is used to measure the viscosity of Newtonian fluids. Shifting the signal of the loop with the adjustable phase-shifter causes sudden jumps in the oscillation frequency of the cantilever. The exact position of these jumps depends … Web6 jun. 2024 · A phase modulated signal of form x (t) can be demodulated by forming an analytic signal by applying Hilbert transform and then extracting the instantaneous phase. This method is explained here. We note that the instantaneous phase is ɸ (t) = 2 π fc t + β + α sin (2 π fm t + θ) is linear in time, that is proportional to 2 π fc t .
