The comb transducer can be considered as the network of the parallel connection of some units of IDT electrical ports and the series connection of their acoustic ports.

A novel micro-scale silicon film bending fatigue testing device based on the electrostatic force by comb driver was designed,which can be fabricated by means of the typical surface micromachining technology.

Finite impulse response comb filter based on fractional delay;

The analysis for comb filter based on crystal birefringence;

A design method for comb filter is proposed,it is demonstrated that the traditional time domain averaging is just a special case of the general comb filter and its performance is influenced by the error of estimating period only.
