Designing and implementing the FPGA algorithm
Up to this point, we have discussed only the details of the digital circuitry needed to receive an analog signal and perform the analog-to-digital conversion. We haven't really looked at what happens to an ADC sample after it has been captured. The next section will provide an overview of all of the functional elements of the digital oscilloscope system.
Digital oscilloscope system overview
Much of our work in the previous chapters has been focused on designing and constructing the hardware aspects of the digital oscilloscope add-on board that will plug into the Arty board. We will now examine the complete system at a high level.
The following figure provides a top-level view of the functional elements of the digital oscilloscope system:

Figure 9.1 shows the portions of the system that reside on the oscilloscope board, those on the Arty A7 board...
