Bucket-brigade transversal filters

IEEE Transactions on Circuits and Systems, 1974
The bucket-brigade delay line (BBDL) is a sampled data circuit in which signal samples are stored and manipulated as packets of charge under the control of a digitally generated clock. The clock-controllable time delay function that is realized by the BBDL may be used to implement a number of signal processing functions.

Fast, recursive-least-squares transversal filters for adaptive filtering

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1984
Fast, fixed-order recursive least-squares (FORLS) algorithms for updating the parameters in linear regression models are presented. The algorithms are derived by using a geometrical approach (more exactly, certain formulas for updating projection operators). Both scalar and multichannel models are considered.

Minimum phase CCD transversal filters

1977 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1977
The calculated and measured response of a minimum-phase CCD low-pass transversal filter is compared to a linear-phase design with the same magnitude characteristics. It is shown that the minimum-phase design can offer up to an order of magnitude improvement in group delay, and is also less sensitive to transfer inefficiency and tap-weight error than ...

PAM pulse generation using binary transversal filters

IEEE Transactions on Circuits and Systems, 1974
Modern narrow-band pulse-amplitude modulation (PAM) and pulse-code modulation (PCM) systems require the generation of precisely shaped pulses in order to avoid intersymbol interference. It is not a simple matter to design analog fiters having pulse responses with the requisite carefully positioned zeros, and this has led researchers to study other ...
