摘要
A surface wave acoustic filter is compensated for diffraction and other spurious effects, which distort its frequency response, by adding an auxiliary acoustic channel which is in parallel with the primary acoustic channel, is out of phase therewith, and mimics the frequency response of the primary channel to the diffracted or other spurious wave.
