Waveform display of a 1.00 kHz sine wave over 5.0 milliseconds, which has been clipped to +6 decibels. Time is on the horizontal axis moving from left to right, and amplitude is on the vertical axis. The amplitude of this sine wave has been increased to a level above its maximum possible positive and negative values, such that the curved positive and negative peaks have been flattened, or
