Energy Per Bit Calculator

How to Use This Calculator

1. Enter the transmission power in watts (W).
2. Enter the data rate in Mbps (Megabits per second).
3. Enter the bit duration in nanoseconds (ns).
4. Click the "Calculate" button to compute the energy per bit.
5. Click "Reset" to clear all inputs and start over.

Working Principle

The energy per bit is calculated by multiplying the transmission power by the bit duration. The bit duration is the time it takes to transmit one bit, which is the inverse of the data rate.

The formula used is:

Energy per bit (E) = Transmission Power (P) × Bit Duration (T)

Where:

• E = Energy per bit (Joules)
• P = Transmission Power (Watts)
• T = Bit Duration (seconds)

Example

If a transmission system has a power of 10 watts and a data rate of 100 Mbps, with each bit lasting 10 nanoseconds:

1. Transmission Power (P) = 10 W
2. Data Rate = 100 Mbps = 100 × 10^6 bits per second
3. Bit Duration (T) = 10 ns = 10 × 10^-9 seconds
4. Energy per bit (E) = 10 W × (10 × 10^-9 s) = 100 × 10^-9 J = 1 × 10^-7 J

This calculator is particularly useful for engineers designing energy-efficient communication systems, helping them balance performance and power consumption.
