Identify the type of wave shown in the diagram and describe one characteristic of a sine wave.
The wave is a sine wave; it has a smooth, periodic oscillation.
The wave is a square wave; it has abrupt transitions between high and low values.
The wave is a triangular wave; it has linear rises and falls.
The wave is a sawtooth wave; it has a sharp rise and gradual fall.
Draw the sine wave after hard clipping.
The sine wave after hard clipping should have its peaks flattened, creating a more squared-off appearance at the top and bottom of the wave.
The sine wave after hard clipping should become a perfect triangle wave with sharp peaks.
The sine wave after hard clipping should remain unchanged, retaining its smooth curves.
The sine wave after hard clipping should become a sawtooth wave with a linear rise and sudden drop.
