Pulse Repetition Time Solution

Follow our step by step solution on how to calculate Pulse Repetition Time?

FIRST Step Consider the formula

T pulse = \frac{2 \cdot R un}{[c]}

Next Step Substitute values of Variables

∴

T pulse = \frac{2 \cdot 8.79km}{[c]}

Next Step Substitute values of Constants

∴

T pulse = \frac{2 \cdot 8.79km}{3E+8m/s}

Next Step Convert Units

∴

T pulse = \frac{2 \cdot 8790m}{3E+8m/s}

Next Step Prepare to Evaluate

∴

T pulse = \frac{2 \cdot 8790}{3E+8}

Next Step Evaluate

∴

T pulse = 5.86405679358351E-05s

Next Step Convert to Output's Unit

∴

T pulse = 58.6405679358351μs

LAST Step Rounding Answer

∴

T pulse = 58.6406μs

f rep = \frac{[c]}{2 \cdot R un}

How to Evaluate Pulse Repetition Time?

Pulse Repetition Time evaluator uses Pulse Repetition Time = (2*Maximum Unambiguous Range)/[c] to evaluate the Pulse Repetition Time, The Pulse Repetition Time formula is defined as the time required by the pulse to reach its target and pulse must travel to the target and back before detection, or twice the range. Pulse Repetition Time is denoted by T_pulse symbol.

How to evaluate Pulse Repetition Time using this online evaluator? To use this online evaluator for Pulse Repetition Time, enter Maximum Unambiguous Range (R_un) and hit the calculate button.

FAQs on Pulse Repetition Time

What is the formula to find Pulse Repetition Time?

The formula of Pulse Repetition Time is expressed as Pulse Repetition Time = (2*Maximum Unambiguous Range)/[c]. Here is an example- 5.9E+9 = (2*8790)/[c].

How to calculate Pulse Repetition Time?

With Maximum Unambiguous Range (R_un) we can find Pulse Repetition Time using the formula - Pulse Repetition Time = (2*Maximum Unambiguous Range)/[c]. This formula also uses Light speed in vacuum constant(s).

Can the Pulse Repetition Time be negative?

No, the Pulse Repetition Time, measured in Time cannot be negative.

Which unit is used to measure Pulse Repetition Time?

Pulse Repetition Time is usually measured using the Microsecond[μs] for Time. Second[μs], Millisecond[μs], Nanosecond[μs] are the few other units in which Pulse Repetition Time can be measured.
