摘要：
This paper proposes a newly derived method to improve the traditional integral method. The trapezoidal integration method (also called the bilinear transform) compensates an improved integral area; therefore, the new numerical integral method is more accurate than the trapezoidal integration method. This new technique can be used to convert an original continuous-time system into an equivalent discrete-time system more precisely. In its application in a digital signal system, the newly generated digital transform has better accuracy than the bilinear transform does. An analysis of the mathematical transformation is given in this paper to show its adjustable characteristics for digital signal systems. An illustrated example was simulated on a real system using the developed method to demonstrate its time-domain response.
