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.

Binary transversal filter

Microelectronics Reliability, 1979
Abstract The present day digital data modems consist of the binary transversal filter (BTF), and a number of logic gates. This paper derives the BTF transfer function from the operational block diagram using shift register as a delay unit. Results are examined particularly from the point of view of the three types of distortion (truncation, aliasing ...

Coefficient Inaccuracy in Transversal Filtering

Bell System Technical Journal, 1979
Coefficient inaccuracy in transversal filters is known to degrade the frequency response, particularly in stopband regions. The magnitude of the stopband degradation increases with the number of stages n, the length of the impulse response. A widely used formula for the error in frequency response is proportional to √n.

Optical transversal filter

Proceedings of the IEEE, 1968
An off-axis optical cavity has been successfully used as a transversal filter in the frequency domain. With a tap spacing of ∼40 nanoseconds, a square wave frequency response has provided alternating pass and rejection bands ∼12.5 MHz wide.

Wideband Agile Transversal Filter

MTT-S International Microwave Symposium Digest, 2005
The development of a Wideband Agile Transversal Filter is made possible by the use of dual gate GaAs FET transistor arrays. The transversal filter design has a bandwidth of greater than 2.0 GHz and the filter transfer function can be changed in less than 10 nanoseconds.
