Ultrasonic waves can be classified into continuous waves and pulse waves based on their duration. A continuous wave refers to a vibration that persists indefinitely in a medium, while a pulse wave is characterized by a limited period of vibration, either as a single burst or in a repetitive pattern.

Definition

A continuous wave is a steady sequence of pulses at a fixed frequency, typically generated by an electro-acupuncture device without any waveform modulation. Its frequency usually ranges between 1 Hz and 1000 Hz. When the frequency is below 30 Hz, it's referred to as a "sparse wave," and when it's above 30 Hz, it's called a "dense wave."

In contrast, a pulse wave is a short-lived, intermittent electrical signal that appears suddenly. Any voltage or current that occurs in discrete bursts is considered a pulse voltage or pulse current. In telecommunications, any waveform that isn't a sine wave or a continuous wave made from sinusoidal components can be classified as a pulse wave.

Function

Pulse waves are less susceptible to interference and can carry encoded information efficiently. Continuous waves, on the other hand, are better suited for detecting targets moving at various speeds. However, achieving similar performance with pulse waves requires more advanced techniques and processing capabilities.

The difference between continuous wave and pulse wave

Waveform Characteristics

One key difference lies in the time domain. A continuous wave has no breaks—it flows uninterrupted. Pulse waves, however, have distinct gaps between each pulse. This makes them appear as isolated spikes rather than a smooth, ongoing signal.

In terms of laser output, a continuous wave means the laser emits light constantly, without interruption. It may be unmodulated or modulated depending on the application. A pulse wave, on the other hand, involves periodic bursts of energy, with intervals where no light is emitted.

Understanding the differences between continuous and pulse waves is essential in fields such as medical technology, communication systems, and industrial applications. Each type offers unique advantages depending on the specific use case and environment.
