    • An apparatus for generating a Carrier-Suppressed Return-to-Zero (CS-RZ) signal is disclosed. The apparatus includes a mixer, a Low Pass Filter (LPF), a driver amplifier and a single external modulator. The mixer generates a modulator input by mixing data with a half clock signal. The LPF band-limits the modulator input data into low frequency band data. The driver amplifier amplifies the modulator input data generated by the mixing of the mixer and the band-limiting of the LPF. The external modulator generates CS-RZ signal, in which the phases of adjacent pulses have been inverted, by applying bias voltage to the modulator input data to be placed at the null point of the transfer function of the external modulator.
    • 公开了一种用于产生载波抑制归零(CS-RZ)信号的装置。 该装置包括混频器,低通滤波器(LPF),驱动放大器和单个外部调制器。 混频器通过将数据与半个时钟信号混合来产生调制器输入。 LPF频带将调制器输入数据限制为低频带数据。 驱动器放大器放大由混频器混频产生的调制器输入数据和LPF的带限制。 外部调制器通过向调制器输入数据施加偏置电压而产生CS-RZ信号,其中相邻脉冲的相位已被反相,以将其置于外部调制器的传递函数的零点。
