    FRF resonant frequencies

    Hi, I'm new here and relatively new to signal processing and analysis. My ultimate goal is to find the mode shapes of a system, but I'm currently working on building the FRF before I move into the next stage. When computing H=Sxy/Sxx (cross power spectrum over input spectrum), I'm getting a...

    Bodeplot of simulation and network analyzer difference in magnitude with same characteristics

    Hello, I have a problem which I can't find the solution. It's related with the determination of the bodeplot of a circuit. According to my bodeplot in the simulation, the flat part of the magnitude plot is -23.02 dB (Simulation.PNG) and the cut-off frequency is equal to 17.67 MHz whereas the...
