This paper provides simple circuit designs that meet those goals ... Figure 4 is a combination block and sequencing diagram that shows the steps a PD goes through when interfacing with a PSE. Figure 4 ...

Block diagrams ... are clear, simple diagrams showing all of the input, process and output elements that make up the system being designed. They are easy to read and show how the circuit will ...

Figure 1 shows a block diagram of the dynamometer’s architecture ... We carefully thought through many design concerns, and I now have an excellent dynamometer to use for motor testing.
