Data from Example 9-8

A technician wires the outputs from a BCD counter to the inputs of the decoder/driver of Figure 9-8. He applies pulses to the counter at a very slow rate and observes the LED display, which is shown below, as the counter counts up from 0000 to 1001. Examine this observed sequence carefully and try to predict the most probable fault.
