Figure 6a: Fast Fourier transform display of the native version of the 11.025 kHz /
16-bit 1 kHz sine wave signal.

Fast Fourier transform display of the native version of the 11.025 kHz / 16-bit 1 kHz sine wave signal. Frequency is on the horizontal axis from 0 to 10.00 kHz, and amplitude is on the vertical axis. The native sine wave is represented in frequency as a high-amplitude spike at the 1.00 kHz location, with no other high-amplitude information.
