Surface Acoustic Wave Filters gives the fundamental principles and device design techniques for surface acoustic wave filters. It covers the devices in widespread use today: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for low bandpass filters are fully covered such as unidirectional transducers, resonators in impedance element filters, resonators in double-mode surface acoustic wave filters and transverse-coupled resonators using waveguides.

The book covers the theory of acoustic wave physics, the...

This is the history of the relationship between mass produced visual media and religion in the United States. It is a journey from the 1780s to the present - from early evangelical tracts to teenage witches and televangelists, and from illustrated books to contemporary cinema.

David Morgan explores the cultural marketplace of public representation, showing how American religionists have made special use of visual media to instruct the public, to practice devotion and ritual, and to form children and converts. Examples include:

• studying Jesus as an American idol
