WebHomodyne demodulation is a convenient technique for signal detection in interferometric sensors. The demodulation process is typically developed using analog circuits. However, to improve the performance of the demodulator, a digital system must be employed. In this study, we developed an optical fiber sensor by combining: (a) a Michelson interferometer, … WebAn AR(p) process {Xt} is a stationary process that satisﬁes Xt −φ1Xt−1 − ···−φpXt−p = Wt, where {Wt} ∼ WN(0,σ2). Equivalently, φ(B)Xt = Wt, where φ(B) = 1−φ1B−···−φpBp. 22
