The concept of linear interpolation in spectral compensation

Content Provider IEEE Xplore Digital Library
Author Maki, C. Chirnitch, J.
Copyright Year 1955
Abstract Spectral compensation is usually achieved with equalizers cascaded so as to generate a desired response. In the concept of linear interpolation, a series of points are located along the desired response and linear interpolation provided between adjacent points. This is accomplished with contiguous band-pass filters arranged so as to minimize the effect of filter crossover. The performance limitations depend upon the filter characteristics, crossover ripple, and the type of response to be equalized. This approach to compensation has two advantages. First, automatic control of the spectrum can be achieved when the input signal is a random noise voltage. Second, discreet points on the frequency axis permit control using digital techniques. Data is presented for some cases of peak-notch resonances encountered in acoustic and vibration systems.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
