Here are the authors original captions for Figures 12, 16 and 17, which were originally in color. 

Figure 12 -- Unmatched (blue) and numerically matched (black) S-parameters of a 10.7 MHz monolithic crystal filter. For comparison, a numerically matched reference measurement obtained on a HP8753C is plotted in red.

Figure 16 -- Unmatched (blue, green) and numerically matched (black) S-parameters of a three pole 11 kHz LC-filter. A measurement of the same filter matched with two 560 ohm series resistors is plotted in red.

Figure 17 -- S-parameters of a 400 MHz crystal surface acoustic wave filter measured with VNWA (blue, green) compared to HP8753C reference measurement (black, red).
