On the sine wave of Figure 11-38(b), mark the points where samples are taken by a flash A/D converter at intervals of 75 μs (starting at the origin). Then draw the reconstructed output from the D/A converter (connect the sample points with straight lines to show filtering). Calculate the sample frequency, the sine input frequency, and the difference between them. Then compare to the resulting reconstructed waveform frequency.
