转换器是一种将声音波形转换为一连串二进制数字的设备，每个数字代表特定瞬间的电压值。

Converters are devices used to convert the waveform into a succession of binary Numbers, each representing the voltage level at a given instant.

此后，将波形序列输入到数字 模拟转换器中（100），其中该波形序列具有在边界处的零偏移。

Thereafter a waveform sequence is input into the digital-to-analog converter (100), wherein the waveform sequence has a zero offset at the boundary.

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.
