摘要：

In this letter, the design of a fractional order FIR differentiator is investigated. First, the fractional derivative of power function is defined. Then, the impulse response of fractional order differentiator is obtained by solving linear equations of Vandermonde form. Finally, one example is used to demonstrate that the fractional derivatives of digital signals are easily computed by using proposed filtering technique.
