The step-line-method of determining frequency response from transient response had been established in Ref.[1], which may only be used for tran sient response to either positive or negative unit step function and unit impulse function. Besides this, the paper has establised more general step-line-method of determining frequency response from transient response which may be used for more general input signals, e.g.half sine waves, triangular waves, square waves, etc.The advantages of this method in comparing with the Bowersox's and Carlson's methods[2] [3][4]are wider scope of application and simplier mathematical operations.
