how to do laplace transform on a signal that is in frequency domain. I have a signal that is in time domain and i used fft to plot it in the frequency domain, is there a way i could plot it in s domain. I know that i could do laplace transform directly from time domain to s domain, but I need to find out are these two results match each other. Fs = 4; % samples per second dt...
