Question

Four waves have pulse repetition periods as listed below which of the following four waves has the lowest pulse repetition frequency?

A. 8 s
B. 80 microseconds
C. 8000 ns
D. 800 ms

Answer 1

The wave with the lowest pulse repetition frequency is option D, with a pulse repetition period of 800 ms.

Step-by-step explanation:

The pulse repetition frequency (PRF) is the number of pulses that occur every second. It is the inverse of the pulse repetition period (PRP), which is the time between consecutive pulses. To find the wave with the lowest pulse repetition frequency, we need to find the wave with the highest PRP.

Looking at the options, the wave with the lowest PRP is D, which has a PRP of 800 ms. To compare it to the other options:

A. 8 s (8,000 ms)

B. 80 microseconds (0.08 ms)

C. 8,000 ns (0.008 ms)

Therefore, option D has the lowest pulse repetition frequency.
