A CMOS Double-Demodulation Lock-In Amplifier for Stimulated Raman Scattering Signal Detection [PDF]

, 2022
In typical stimulated Raman scattering (SRS) signal extraction, the photodetector and lock-in amplifier are often based on separate platforms, rendering the system cumbersome and non-scalable.

Resonance-Based Nonlinear Demodulation Analysis Method of Rolling Bearing Fault

Advances in Mechanical Engineering, 2013
Numerous mechanical nonstationary fault signals are a mixture of sustained oscillations and nonoscillatory transients, which are difficult to efficiently analyze using linear methods. We propose a nonlinear demodulation analysis method based on resonance
