Figure 8.30. The input goes to the inverting input of a comparator. The output of the comparator goes to a block labeled control logic. The output of this block is a wide line indicating many lines carrying binary data. It is labeled control bus. The control bus goes to a block labeled binary register. Coming out of this block is another wide line labeled data bus. It goes to a block labeled D A C for digital to analog converter. The output of the D A C goes to the noninverting input of the comparator. The data bus also goes to a point labeled data output. End verbal description.
