Setting Parameters
1. With the Parameters tab selected, specify the generation algorithm, precisions,
phase dithering, and generated output frequency parameters.
As you adjust these parameters, you can graphically view the effects on the NCO
MegaCore function in the Frequency Domain Response and Time Domain
Response tabs as shown in Figure 3–1 on page 3–3 .
The NCO MegaCore function generates the spectral plot shown in Figure 3–1 by
computing a 2,048-point fast Fourier transform (FFT) of bit-accurate time-domain
data. Before performing the FFT, IP Toolbench applies a Kaiser window of length
2,048 to the data.
You can zoom into the view by pressing the left mouse key on the plot drawing a
box around the area of interest. Right-click the plot to restore the view to its full
range.
Refer to “Architectures” on page 4–4 and “Phase Dithering” on page 4–8 for more
information about these parameter options.
