Hello,
I need to compute a time synchronous averaging to a noisy output signal in sine sweep measurement. Can't figure it out how to compute it? Any tips would very much appreciate.
Thanks in advance.

Is it possible for you to just avoid getting the noise in the first place by using a lock-in amplifier? http://en.wikipedia.org/wiki/Lock_in_amplifier

Hi..thanks for that, although my tutor wants us to analyze the frequency response of a noisy input signal by using the sine sweep measurement using matlab. I need to use the time synchronous averaging to the output signal, the noisy signal before I do any (de)convolution. I found a code but it's all quite confusing still..
Any tips would be great..

Morning, I am working on a vibration signal also , and I want to used the TSA to avoid the noise and to get a pure signal . But I can't neither find the code , nor the deal with. Ps: I work on MATLAB R2017a Any help please and I will be grateful for that. Chokran (Thank you)
