| Abstract: | A new method of digital signal processing: matrix pencil method is introduced in this paper. Fundamental principle of the matrix pencil method, the Moore Penrose generalized inverse or pseudoinverse and singular value decomposition of a matrix are narrated. The calculation formulas of the matrix pencil method are deduced and the effects in noise reduction of the matrix pencil method in impulse voltage digital measurements are studied. Finally, it is pointed out that the matrix pencil method is quite an effective algorithm for the exponential and exponential oscillating impulse voltage and the measuring accuracy in impulse voltage digital measurements can be greatly improved with the matrix pencil method. |
