PoZeTools v0.56

Enter your poles and zeros [and an optional gain] below:
# Tenth-order combfilter with maximal delay: p = 0.98 p = 0.98 exp (0.2 pi j) p = 0.98 exp (0.4 pi j) p = 0.98 exp (0.6 pi j) p = 0.98 exp (0.8 pi j) p = -0.98 p = 0.98 exp (1.2 pi j) p = 0.98 exp (1.4 pi j) p = 0.98 exp (1.6 pi j) p = 0.98 exp (1.8 pi j) # Empty lines and lines starting with # are ignored. Supply- # ing no gain invokes auto-normalization. Both polar and # cartesian notations are accepted. The order in which poles, # zeros and the (complex) gain appear does not matter. # Some valid lines are: P = 0.98 exp(-0.25 pi j) # P = j - 0.88 # Z = -j # Z = 0.6 + 0.6 j # G = exp(-j pi)
Read 0 zeros and 10 poles. No gain supplied, automatically normalizing.
