Abstract: | The method presented in this letter converts frequency-response data into an analytical expression for the impulse (step response) as a linear combination of polynomials whose coefficients are given. The constants of this linear combination are, instead, the coefficients of the Cheby?shev approximation of the real (or imaginary) part of the frequency response. |
