Example Tapped Delay LineAn example of a TDL with two internal taps is shown in Fig.2.19. The total delay line length is samples, and the internal taps are located at delays of and samples, respectively. The output signal is a linear combination of the input signal , the delay-line output , and the two tap signals and .
difference equation of the TDL in Fig.2.19 is, by inspection,
