By approaching each approximation function in the same manner, and developing methods for determining exact pole and zero placement, we have simplified the job of generating the C code necessary to implement these algorithms in a clean, efficient manner. ) In the next chapter, we will finish up the analog filter design calculations by determining a technique to unnormalize the transfer functions we have just developed. Chapter 3 Analog Lowpass, Highpass, Bandpass, and Bandstop Filters In the last chapter, we were able to determine the normalized approximation functions for the most common types of analog filters.
Although the Chebyshev and inverse Chebyshev filters provide the same gains at the passband and stopband edge frequencies, their responses are not identical. If we were to take a close look at the frequency response in the passband, we would find that the inverse Chebyshev provides a better approximation to the ideal response except at frequencies very near to 1 (the normalized passband edge frequency). In that case, the standard Chebyshev produces a tighter fit. In the transition band, the standard Chebyshev response provides a more rapid transition.
In this formulation, note that it is the ratio of the stopband and passband frequencies which is important, not either one of these independently. This means that a filter with a given set of gains will require the same order whether the edge frequencies are 100 and 200 rad/sec or 100,000 and 200,000 Hz. 3 Butterworth Pole Locations The poles for a Butterworth approximation function are equally spaced around a circle in the s-plane and are symmetrical about the jω axis. Plotting the poles of the magnitude-squared function |H(s)|2 shows twice as many poles as the order of the filter.
