What term defines a nonpulsed wave in which cycles repeat indefinitely?

Explanation:
In ultrasound, a continuous wave is produced when the transducer emits energy without turning off, so cycles repeat indefinitely. There are no gaps between cycles, giving a steady, ongoing oscillation. This distinguishes it from a pulsed wave, where energy is emitted in bursts with listening times in between. The other terms don’t describe this continuous, unbroken emission: compression is just a high-pressure portion of a wave, a cycle is a single oscillation, and attenuation is the loss of signal strength as it travels.
