WebDec 20, 2024 · Looking at the first peak, we see a width of 0.047 minutes or approximately 2.8 seconds. With a Sampling Rate of 20 points per second, there are 56 points across the peak, which is more than enough. Mass detectors adjust the sampling rate in the instrument method based on the mass range that you specify. That means for large mass ranges the ... WebLet’s take a look at two different rooms. In one, the average signal strength is -20, the noise is around -60. To get the signal to noise ratio, it’s the signal minus the noise, which means we have an average signal to noise of 40 in this case: Signal to Noise Ratio. How about room 2, where the signal is also -20, but the noise is -25.
