The objective of this experiment was to design a digital chebyshev filter from analog chebyshev filter. Here we take inputs like pass band attenuation, stop band attenuation, pass band, stop band and sampling frequencies in hertz. We implemented calculations of all parameters of the chebyshev filter in scilab.
After plotting the digital filter, the values of pass band and stop band attenuation were verified. As the values were not matching, it was concluded that after increasing the order of the filter, we get better matching between input and output values.
We performed type 1 filter. Hence we got ripple in pass band.
ReplyDeleteyes tejashree...so it is chebyshev 1 filter
ReplyDeleteIn the magnitude response of the Low Pass Filter, there is ripple in the pass band whereas the stop band is monotonic and there is no ripple. In the magnitude response of the High Pass, there is ripple in the stop band whereas the response is monotonic in the pass band.
