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 ... WebFeb 17, 2024 · Signal-to-Noise Ratio (SNR) measures the strength of the desired signal relative to the background noise, which is an undesired signal. SNR is imperative to distinguish various output signals to achieve efficient output. Signal-to-Noise Ratio is typically expressed in terms of decibels. The higher the SNR value, the better is the output.
