Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Exponential Settling Time from Decay Requirement to answer this question: calculate settling time from required positive decay exponent and positive exponential decay rate? Enter required positive decay exponent and positive exponential decay rate; the calculator shows settling time. For example: required positive decay exponent=4 and positive exponential decay rate=0.8 produce settling time=5. The answer tells you settling time.

Age 15Explain it to a 15-year-oldConnect it to the formula

An exponential envelope reaches exp of minus the required exponent after exponent divided by decay rate time. This page evaluates the relationship directly. The rule is c=a/b. Its input values are required positive decay exponent, positive exponential decay rate, and the main result is settling time. For example: required positive decay exponent=4 and positive exponential decay rate=0.8 produce settling time=5.

CollegeExplain it at college levelState the model precisely

This calculator evaluates the stated exponential settling time from decay requirement relation over the valid real-number domain stated below. The implemented relation is c=a/b, evaluated from required positive decay exponent, positive exponential decay rate to produce settling time. An exponential envelope reaches exp of minus the required exponent after exponent divided by decay rate time. This page evaluates the relationship directly. The familiar two-percent settling approximation uses a required exponent near four.

Inputs and valid domain

  • required positive decay exponent must be a finite real number.
  • positive exponential decay rate must be a finite real number.

Important boundary: The familiar two-percent settling approximation uses a required exponent near four.

The formula

c=a/b

How the calculator works through it

It substitutes required positive decay exponent, positive exponential decay rate into the formula and exposes every numerical step above. The main output is settling time.

Read the result correctly

The settling time is the direct answer to “calculate settling time from required positive decay exponent and positive exponential decay rate.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.

A worked check

required positive decay exponent=4 and positive exponential decay rate=0.8 produce settling time=5.

Where this model stops being reliable

The familiar two-percent settling approximation uses a required exponent near four.

Learn it by changing one value

Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
