-#X text 16 58 This patch demonstrates using the raw filters \, rpole~
-and rzero~ (raw \, real-valued one-pole and one-zero filters) \, to
-make a shelving filter.;
-#X text 14 109 If the pole is at p and the zero is at q \, the gain
-at DC is (1-q)/(1-p) and the gain at Nyquist is (1+q)/(1+p). If the
-pole location is close to plus or minus one \, this can give large
-gains unless q is in the same vicinity. (try \, for example \, p=90%
-\, q=70%).;
-#X text 11 191 The crossover region varies from DC to Nyquist as p
-and q decrease from 100% to -100%.;
