6.7 PCB check and adjustment
6.7.1 Guide to PCBs and logic diagrams
Circuit diagrams contain input and output signal names (mnemonics), coordinate
locations of rcs, input origines, destination coordinates of output signals, IC
pin numbers and rc types. Figure 6.7.1 shows how to read circuit diagrams.
