Consider an exponential function y(t) = y(0)e^-omegat + noise Let the parameters be y(0)=10; alpha=1.25 How to apply curve fitting?

Solution

n=input(\'Enter the duration of the signal N = \');
a=input (\'Enter the scaling factor a = \');
t=0:.1:n-1;
y(t)=y(0)exp(-a*t)+noise ;
plot(t,y);
ylabel (\'Amplitude\');
xlabel (\'Time Index\');
