Abstract :
A hybrid combination of an acoustic surface wave tapped delay line and semiconductor switching devices is used to generate bi-phase coded sequences and to serve as the matched filter for these sequences. The switches permit the phase of a tap to be changed by 180/spl deg/ so that complete code flexibility is achieved.
