另一方面，为了兼容其他那些工作输入信号电压不为0的器件，如模数-数模转换器，信号电平也许要做平移。

On the other hand, the signal may require level shifting in order to be compatible with the input of other devices (such as ADCs) that are not designed to operate at 0v input.

自从70年代微处理器出现以后，利用微处理器、模数转换器和数模转换器，硬件和软件使信号发生器的功能扩大，产生比较复杂的波形。

Since the 1970s a microprocessor, the use of microprocessors, ADC and DACs, hardware and software to expand the functions of the signal generator, a more complex waveforms.
