A Stepped Frequency Sweeping Method for Nonlinearity Measurement of Microresonators

A Stepped Frequency Sweeping Method for Nonlinearity Measurement of Microresonators

In order to measure the nonlinear features of micromechanical resonators, a free damped oscillation method based on stair-stepped frequency sinusoidal pulse excitation is investigated. In the vicinity of the resonant frequency, a frequency stepping sinusoidal pulse sequence is employed as the excita...
