Bandwidth Time Product | Time Bandwidth Product | BT

This page describes bandwidth time product basics.The bandwidth time product is also denoted by BT.

What is Bandwidth Time Product (BT)?

• It is the product of spectral width (BW) and signal duration(T).
• Usually signal with short duration has wider spectral width and vice versa.
• As we know to transmit certain amount of data over given bandwidth needs certain time.
• The Bandwidth time product measures how effectively we are using available bandwidth (BW) for given channel.
• It is expressed as follows.

Bandwidth Time Product

Time variance = 0.5
Frequency variance = 0.5
Bandwidth time product (BT) = 0.25
