The duty factor for continuous wave ultrasound is _____, because the system is always ______.

Explanation:
Duty factor is the fraction of time the system is actively transmitting during a cycle. In continuous-wave ultrasound there are no gaps—it's transmitting all the time—so the duty factor is 100%. The fact that it can also receive doesn't change this, because the measure focuses on how long the transmitter is on. In pulsed ultrasound, transmission is on only for part of the cycle, yielding a duty factor less than 100%.
