Monolithic Surface Wave Transversal Filter
1977 Ultrasonics Symposium, 1977Abstract : A monolithic surface wave transversal filter was designed, fabricated, and evaluated. The semiconductor and acoustic elements were developed on (001) p-type silicon oriented for acoustic transmission along the (100) direction. Surface acoustic waves were generated by zinc oxide film layer transducers into an array of 31 metal-gate NMOS ...

Transversely coupled resonator filters
1999 IEEE Ultrasonics Symposium. Proceedings. International Symposium (Cat. No.99CH37027), 1999Transversely Coupled Resonator Filters (TCRFs) have become an important type of low-loss filters with narrow bandwidth. Their basic layout consists of two one-port resonators arranged acoustically in parallel. Therefore a mechanism that couples both original resonators with each other is necessary.

Transversal Filters for Pulse Spectroscopy
IEEE Transactions on Nuclear Science, 1975Transversal filtering consists of forming an output signal from the suitably weighted sum of successively delayed samples of a given input waveform. Although such filters exhibit many attractive features, economic considerations have previously limited their hardware implementation to rather few areas, primarily the fields of communications and radar ...

Spatial Filtering to Improve Transverse Tomography
IEEE Transactions on Biomedical Engineering, 1974A new transverse tomographic apparatus is described that enables the tomogram to be related to the ideal image by a linear blurring operation. It is shown that digital and optical linear spatial filtering techniques may be employed to remove the blurring that is present in the tomographic image obtained with the new device. Experimental verification of

Transversal narrowband switched-capacitor filters
Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002This paper considers the implementation of non-recursive switched-capacitor filters realized in transversal form for narrowband signal processing applications. Effects of random capacitance errors and finite gain and bandwidth of the operational amplifiers in the filter frequency response are investigated.

1986
This chapter takes a different approach to fast recursive least squares (RLS) filtering, and applies the projection techniques and vector space methods to the derivation of fixed-order, transversal least squares (LS) filters. The resulting algorithm will be denoted as the fast transversal filter (FTF).

Optimization of Binary Transversal Filters
IEEE Transactions on Communications, 1983This paper presents a method for optimization with respect to bandwidth efficiency for a binary transversal filter when the input pulse format is NRZ. The objective is to concentrate as much as possible of the energy in the emitted signal within certain frequency bands. The filter coefficients are given by a symmetric eigenvector for a Toeplitz matrix,

Analog Binary Programmable Transversal Filter.
1979Abstract : The objective of this program is to develop a programmable CCD (Charge-Coupled Device) circuit capable of correlating a variety of binary-coded waveforms. This analog-binary correlator will store a binary waveform as a reference, and will then compare newly arriving signals to the reference waveform.

Acoustic Adaptive Transversal Filter.
1976Abstract : The availability of spectral information in real-time clearly permits many important new signal processing applications. Although understanding the basic operating principles of the Transform Adaptable Processing System is more complex than is the case for a conventional programmable filter, its physical implementation is considerably ...

Transversal filters with continuously tapped delay lines (CTT filters)
Proceedings of the IEEE, 1969The properties of common transversal filters are well known. Transversal filters with continuously tapped delay lines have the advantage that they do not show a periodic continuation of the frequency characteristic. Therefore it is not necessary to use an additional filter for suppressing higher frequency components. After an introduction to CTT filter
