Linear Networks with Delays

Tapped Delay Line

We need a new component, the tapped delay line, to make full use of the linear network. Such a delay line is shown below. There the input signal enters from the left, and passes through N-1 delays. The output of the tapped delay line (TDL) is an N-dimensional vector, made up of the input signal at the current time, the previous input signal, etc.
