a(h+i)=a(h)*exp(-n1/Td),i=1,2,3...,p;

where a(h) is the amplitude of the signal at time h, n1 is the time constant of the decay process, Td is the sampling interval, and p is the number of samples in the signal.

This equation describes an exponential decay process where the amplitude of the signal decreases over time. The decay rate is determined by the time constant n1, which represents the time it takes for the amplitude to decrease to 1/e of its original value.

The equation is often used in signal processing and analysis to model decay processes in various systems, such as electronic circuits, chemical reactions, and biological systems. By fitting this equation to experimental data, researchers can estimate the time constant of the decay process and gain insights into the underlying mechanisms of the system.
