Title: Matching filter
Inventor: SHINONAGA HIDEYUKI
IPC: H03H9/64
Filed: 1989-10-11
Abstract: PURPOSE:To bring a shape of an envelope of a compression pulse and an impulse reply pulse close to a desired shape by increasing a gap between a tap of an output side interdigital electrode and a dummy electrode wider than a gap between electrode fingers forming the tap. CONSTITUTION:A gap D between a tap 4 and a dummy electrode 7 is selected wider than a gap (g) between electrode fingers 5 forming the tap 4 as twice the gap (g). The strength of the electrode field caused at both sides of the 1st dummy electrode 7 shown in dotted lines is smaller than the strength of the electric field caused between the electrode fingers 5 shown in solid lines. Thus, when an electric signal is applied to an output side interdigital electrode 3, the difference of the electric field strength caused between the taps is small. Then when a surface acoustic wave excited by an input interdigital electrode is made incident in the output side interdigital electrode 3, the dispersion in signal reception for each tap 4 having caused in a conventional filter among electric signals received by each tap 4 is decreased and the shape of an envelope of a compression pulse and an impulse reply pulse is made close to a desired shape.
