Tuning of Group Type Unidirectional Transducers
Donald C. Malocha, B.J. Hunsinger · IEEE Transactions on Sonics and Ultrasonics · 1979
Abstroct-A simple tuning network is presented for tuning of group type unidirectional transducers. The method of tuning described uses a maximum of two elements and in special cases requires only a siigle external element. Experimental results for a filter having a 6.3dB insertion loss and a triple transit echo suppressed -44 dB using the described method verifies the analysis.
