The transfer function of a Chebyshev filter is characterized by a number of ripples in the passband .It has a smaller transition region than the same order Butterworth filter, at the expense of ripples in its pass band. The Chebyshev response is a mathematical strategy for achieving a faster roll-off by allowing ripple in the frequency response. The basic concept of a filter can be explained by examining the frequency dependent nature of the impedance of capacitors and inductors. The significance of this work is the introduction of a new concept used to fabricate low-pass filter which is using laser micromachine.
