Abstract :
Surface wave multichannel bandpass filters such as the selectable filters, filter trees, or filter banks provide a large number of bandpass filter channels with relatively few transducers. Among major systems applications are frequency-hopped receivers, spread-spectrum equipment,and multichannel multiplex systems. Synthesis of more than 100 bandpass responses of varying center frequency and varying bandwidth with nominally 20 transducers is detailed.
