Abstract
銆?/p>
By using the theory and design method of digital filter
锛?/p>
the IIR digital filter is
designed by impulse response method and bilinear transformation method in Matlab software
development environment
锛?/p>
and with the help of Matlab GUI
锛?/p>
the human-computer interaction
interface of IIR digital filter is designed
锛?/p>
the system interface is simple and intuitive
锛?/p>
easy to be
operated and complete function
锛?/p>
and de-nosing process of voice signal is realized. Comparing the
simulation results
锛?/p>
the results show that Chebyshev
鈪?/p>
type has much more function of de-nosing
process of voice signal.
