Correction to "Direct-Coupled Cavity Filters for Wide and Narrow Bandwidths" (Correspondence)

In the above paper, on page 170, the /spl Delta/ symbols were omitted in (34) and (35). On page 176, the caption to fig. 24 should be: Characteristics in the stop band of the quarter-wave transformer prototype and the two filters (B and C in Fig. 23) derived from it.
