dsPIC30F Demonstration Program Operation
Figure 3-7 depicts the flow of data from the time the analog input is converted by the
dsPIC30F device to the time the frequency is estimated.
FIGURE 3-7:
Figure 3-8 shows the frequency response of the IIR filter implementation. The IIR filter
is only employed for demonstrating filter operation.
