Following that, we’ll present examples of how to calculate and interpret the SNR in different scenarios. 2. How to Compute the SNR? 2.1. Definition The SNR represents the ratio between the signal and the background noise. If we have a high SNR, it means that the strength of our signal...
In order to calculate the duty cycle, we need to first find the frequency or period of the variable signal. This can be found with multiple methods, but the initial approach can be to measure the pulse width of the transmitted signal. To do this with an unknown signal, we can connect t...
No, of course not. To determine or even estimate the Signal to Noise ratio, you have to distinguish the Signal and the Noise. If you do not have further information, this is impossible. If you know, that the signal is e.g. a clean sine wave, su...
Sometimes, when using a modal impact hammer to calculate an experimental FRF, a user may apply an Exponential Window to avoid leakage effects to the accelerometer signal. The accelerometer response is multiplied the exponential window causing it to decay quicker in time, thus increasing the apparent...
