DSPP EXP 6 Design of Chebyshev Filter

Just like the previous experiment even this one was performed using Scilab. The procedure here is pretty much the same as that of Butterworth, by giving the input specification we plot the magnitude plot for High pass and Low pass filter. But in this case unlike the butterworth filter plot, ripples were observed in the passband while the stop band was monotonic.It was also observed that the order of the filter was less in chebyshev as compared to butterworth for the same input parametres. Hence chebyshev filter requires less hardware.
