Withdrawal weighting has proved to be a useful scheme for obtaining a desired impulse response from a surface acoustic wave transducer. However, fpr many weighting functions, especially in broadband devices, the withdrawal weighting procedure results in relatively large portions of the transducer having n o fingers. As a result, the withdrawal pattern is a… CONTINUE READING
