Nettet19. mai 2024 · 2. If in log-space the decaying part of the data does not look linear, then it is not a simple decay. Actually the data looks more like a sum of an exponential decay and a constant background. So try a model like a*exp (-b*x)+c. The curve in the picture is the right hand side of a gaussian peak (the tails fall more or less exponentially) with ... NettetExponential decay. A quantity undergoing exponential decay. Larger decay constants make the quantity vanish much more rapidly. This plot shows decay for decay constant ( λ) of 25, 5, 1, 1/5, and 1/25 for x from 0 to 5. A quantity is subject to exponential decay if it decreases at a rate proportional to its current value. grandstream phone transfer to voicemail
