    摘要: A binary transversal filter (200) in which the delay line of flip-flops (A-L, Aʹ-Lʹ) is clocked by timing signals (CLK, CLK*, CLKD, CLKD*) that are phases of the clock (CLK) that introduces encoded binary signals (IMPULSE 0, IMPULSE 1) into the delay line (A-L, Aʹ-Lʹ). Weighing means (RA-RL, RAʹ-RLʹ) weigh the output of each of the stages of the delay line. The weighted outputs are summed (Q2) to form a synthesized output and in a radio frequency transmitter are passed to a programmable amplifier (210), the gain of which is turned on when there is data in the encoded binary signals (IMPULSE 0, IMPULSE 1) to be converted and transmitted, and is turned off otherwise.
