Step 1 of 2 8.078E Refer Tables 8-34 and 8-35 from the textbook. The output waveforms produced by the ABEL programs are not similar though both the programs account for a one-tick decoding delay between each transition. The states are different for the both. The state difference is shown in table 1.
