PREFACE

This guide deals with the major factors and new techniques in filters and attenuators. The problems inherent in this field are discussed fully, step-by-step, as a technician would encounter them on the job.

Detailed attention is given to the general characteristics of low-pass filters, choke-input filter systems, capacitor-input filter systems, tuned low-pass filters, graded filters and cancellation filters.

The problems of audio filters and radio and television filters receive special attention, with special emphasis on decoupling filters, tone controls, speech clipping, high-fidelity filters, Scott filters and high- and low-frequency compensation filters. The problems of traps in television receivers, transmission filters, noise filters, crystal filters and interference filters are also fully discussed.

We have covered large areas such as wave filters and attenuators and equalizers and given special treatment to filter classifications, characteristic impedance, filter configurations, constant-k and derived-m filters, and a host of others dealing with configurations.

Bridged-T and parallel-T networks and their applications are fully dealt with.

Attenuators and equalizers are discussed, ranging from definitions and examples of fixed attenuators through amplitude equalizers, phase equalizers and resistance pads, noting their types and design.

Through these discussions the earnest reader will establish a foundation for advanced concepts.

Grateful acknowledgment is made to the staff of the New York Institute of Technology for their assistance and cooperation.

New York, New York, USA. April, 1961, A.S.
