Which of the following best describes the shape of a sinusoidal wave signal during one complete cycle?

Correct option is B

The correct answer is (b) S-shaped wave

• A sinusoidal wave (or sine wave) has a smooth, continuous wave shape that is typically represented as an S-shaped curve.

• During one complete cycle, the wave starts from zero, rises to a positive peak, returns to zero, dips to a negative peak, and then returns to zero again, forming the characteristic S-shaped pattern.

• The sinusoidal wave is mathematically defined by the sine or cosine function, and is commonly used to represent AC signals and other periodic phenomena.

Information Booster:
• Sinusoidal Wave: This wave is the foundation of many signal processing techniques and is essential in understanding periodic signals.
• Frequency: The number of cycles per second is called the frequency of the sine wave.
• Amplitude: The peak height of the sine wave is its amplitude, representing the signal's strength.

Additional Information:

• (a) Triangular Wave: A triangular wave is a linear ramp that alternates between positive and negative peaks in a triangular shape.

• (c) Square Wave: A square wave consists of sharp transitions between two levels, producing a rectangular appearance with no smooth curve.

• (d) Rectangular Wave: Similar to the square wave, but with different durations for the high and low phases, still not sinusoidal.
