5 Matching Questions
- Pulse Repetition Period
- Amp.
- Pulse Repetition Frequency
- Duty Factor
- Directly proportional to Amp squared
- a the number of pulses that occur in 1 sec.
- b power
- c the time from the start of the one pulse to the start of the next
- d fraction/% of time that a pulsed u/s is on or transmitting (unitless)
- e It's units depend on the acoustic variable (decreases exponentially as sound propagates thru body
5 Multiple Choice Questions
- cycles & deadtime
- a collection of cycles with a beginning and end
- on, transmitting, sending time
- time from the start of a pulse to the end of "that" pulse
- (temporal peak) max. I found in the pulse @ an instance in time
5 True/False Questions
-
TA → (temporal avg) avg. I during PRP (transmit and receive times) related to DF
-
deadtime → (pulse avg) avg. I during PD includes beginning (increased value) & near end (decreased value)
-
Pulse u/s → a collection of cycles with a beginning and end
-
SPL → determined by source & medium (like wavelength)
-
Power → aka: the time-of- flight of a sound pulse btwn xdcr and botton of image
