A pulse with 4 cycles and a period of 2 μs per cycle has a pulse duration?

2 μs

8 μs

Pulse duration is the total time the ultrasound transducer is actively emitting during a single pulse. It equals the number of cycles in the pulse multiplied by the period of each cycle. With four cycles and a period of 2 microseconds per cycle, the duration is 4 × 2 μs = 8 μs. So the pulse duration is 8 μs.

4 μs

6 μs
