![]() So, it is also referred as a maximally flat magnitude filter. Butterworth FilterĪt the expense of steepness in transition medium from pass band to stop band this Butterworth filter will provide a flat response in the output signal. For slow transition from pass band to stop band the Chebyshev filter is designed and for maximum flat time delay Bessel filter is designed. By taking these considerations for each consideration one type of filter is designed.įor maximum flat response the Butterworth filter is designed. In addition to these three the rising and falling time parameters also play an important role. These distortions are generally caused by the phase shifts of the waveforms. ![]()
