Abstract
A digital transversal filter includes first and second shift registers. A first digital data signal is applied as an input to the first shift register and a second digital data signal, which is a phase shifted version of the first digital data signal, is applied to the second shift register. First and second clock signals are used to clock the shift registers, and these clock signals correspond in frequency but differ in phase with respect to one another. The outputs of the stages of the first and second delay lines are weighted by respective resistors which are connected to a summing node. The digital data signal has a data clocking rate, the first and second clock signals have a delay line clocking rate, and the data clocking rate is slower than the delay line clocking rate.
