I would like to have an identical mapping of the timestamps in the input, to a frequency level in the output. Focus: Time domain analysis emphasizes the transient response of a system, studying how the system behaves over time. The time domain, for example, is not nearly so easy to access as it requires the inverse Laplace transform. Representation: In time domain analysis, signals are represented as functions of time, while in frequency domain analysis, signals are represented as functions of frequency. You can also extract system characteristics such as rise time and settling time, overshoot, and stability margins. You don't need to fft.
