Abstract :
In this correspondence, we will derive an expression for group velocity in a transmission line by using its filter-type equivalent circuit. The expression will be an exact formula for group velocity and different from the traditional approximate expressions, which are found in the text books. We will discuss a special case of this expression, where it can be expressed in a simplified manner.
