Appendix H. Frequency Sampling Filter Design Tables

In Section 7.1 we described the so-called Type-IV frequency sampling filter (FSF). The tables in this appendix provide a list of optimum transition coefficient values for the Case I (see Figure 7-25) Type-IV lowpass FSFs of various passband bandwidths, over a range of values of N. Table H-1 provides the H(k) single transition coefficient and two transition coefficients for even values of N. Table H-2 provides the H(k) three transition coefficients for even N. Table H-3 provides the H(k) single transition coefficient and two transition coefficients for odd values of N, while Table H-4 provides the H(k) three transition coefficients for odd N.
