Fig.4 Example FX002 Input/Output Relationships

The diagrams in Figure 4 are example spectrums of the input and output signal conditions of the FX002.

Note that the frequency of the output signal is four times (x4) that of the input signal.

Fig.5 Enhancement of Signal-To-Noise Ratio

The graph shown in Figure 5 illustrates the signal-to-noise enhancement that can be obtained, under varying

input conditions, from the FX002.
