ABSTRACT:
For a convolver to be operated with an input signal E and with two reference signals A and B, two convolver tracks (or four tracks given self-convolution compensation) are required having input transducers connected in parallel for the input signal E in comparison to the transducers for input of the reference signals A and B. All transducers have fundamentally a same design. However, modified split-finger transducers with floating fingers are provided for the input signal transducers, whereas non-modified split-finger transducers are provided for the reference signals.
