Chapter 3 Flashcards
1
Q
PD
A
Pulse Duration
The time from start to end of a pulse
2
Q
Pulse Duration equation
A
PD = # cycles in pulse x period
PD = (#cycles in pulse)/(period)
3
Q
PRP
A
Pulse Repetition Period
Start of one pulse to the start of another pulse
4
Q
PRF
A
Pulse Repetition Frequency
PRF is the number of pulses that occur in one second
5
Q
PRP and PRF relationship
A
They are reciprocals
6
Q
PRP and PRF equation
A
Reciprocal triangle
7
Q
DF
A
Duty Factor
The percentages or fraction of the time that the system transmits sound
8
Q
Duty factor equation
A
Duty factor% = [(PD) / (PRP)] x 100
9
Q
Spatial Pulse Length
A
The length or distance that an entire pulse occupies in space
10
Q
SPL Equation
A
SPL = # of cycles x wavelength
