Hello I excite a system with a sine wave at a fixed frequency and I have the signals of excitation and response. What is the best way to calculate the magnitude and phase of the system at this frequency? (Similarly to a frequency response estimation, but with only one chosen frequency).
Hi everyone, I have learnt a lot about LabVIEW programming from this website and this forum. However, this is my first post on the forum. So I have managed to get a signal, which is in time domain, with the amplitude in volts. It looks like the in the picture attached. The above signal is the raw signal, and the one below is a cropped section of the part of the above signal I am interested in. The increase in amplitude seen in the cropped section is an "echo" of the transmitted signal. The cropped signal starts again from time=0, but that can be taken care by simply adding the time, a
