- The centre frequency is determined by the pitch of IDT comb shaped electrodes
- The response can be modified shaping the overlap of comb electrodes
- The response is maximum when acoustic wave has its wavelength equal to pitch
- When a number of identical electrodes are arranged at the same pitch, the frequency characteristics of the filter is expressed by (sin x)/x
Consider the following statements as regards SAW filter
