Here is how the Information Rate equation looks like.

1800 = 1000 \cdot 1.8

1800b/s = 1000b/s \cdot 1.8b/s

1800 = 1000 \cdot 1.8

Information Rate Solution

Follow our step by step solution on how to calculate Information Rate?

FIRST Step Consider the formula

R = r s \cdot H[S]

Next Step Substitute values of Variables

∴

R = 1000b/s \cdot 1.8b/s

Next Step Prepare to Evaluate

∴

R = 1000 \cdot 1.8

LAST Step Evaluate

∴

R = 1800b/s

Formulas to find Information Rate

Symbol Rate

Symbol Rate refers to the number of symbols transmitted per second in a digital communication system.

Symbol: r_s

Measurement: Data TransferUnit: b/s

Note: Value should be greater than 0.

Formulas to find Symbol Rate

Entropy

Entropy is a measure of the uncertainty of a random variable. Specifically, it measures the average amount of information contained in each possible outcome of the random variable.

Symbol: H[S]

Measurement: Data TransferUnit: b/s

Note: Value should be greater than 0.

FAQs on Information Rate

What is the formula to find Information Rate?

The formula of Information Rate is expressed as Information Rate = Symbol Rate*Entropy. Here is an example- 1800 = 1000*1.8.

How to calculate Information Rate?

With Symbol Rate (r_s) & Entropy (H[S]) we can find Information Rate using the formula - Information Rate = Symbol Rate*Entropy.

Can the Information Rate be negative?

No, the Information Rate, measured in Data Transfer cannot be negative.

Which unit is used to measure Information Rate?

Information Rate is usually measured using the Bit per Second[b/s] for Data Transfer. Kilobit per Second[b/s], Kilobyte per Second[b/s], Megabit per Second[b/s] are the few other units in which Information Rate can be measured.
