according to the given response specification, and •-is the width of the window, namely, the length of the pulse response. The results of synthesizing SAWF by means of the new window function are reported. In synthesizing, one unapodized transducer and one length-weighted transducer are used. The transducers have a double electrode structure with each half of the double electrode individually weighted.3:00 GG6. Loudspeaking telephone using echo eanee!!ers and a voiceswitching circuit.
