- Abstract:
- A new method to determine the exponential components of a signal using the maximum likelihood method will be presented in this paper. The exponential stimulus signal is assumed to be distorted by superimposed exponential components with longer time constant and smaller peak value. The exponential signal to be identified is acquired by a general purpose DAQ board. The advantage of the proposed method is lower sensitivity to the additive noise and restriction of the signal processed to the full scale range of the ADC. The sensitivity of the proposed method on the measurement and processing conditions is studied theoretically and by simulation.
