    摘要: A fluid flow control system has a fluid source and plural flow pipes connected to the fluid source. Each of the pipes has an opening of a specific area corresponding to one of the bit orders of a PCM (Pulse Code Modulated) input signal. The flow-condition of the fluid through each of the pipes is controlled by the PCM signal without changing the PCM signal to an analog signal. The summation of the outflow from each of the pipes combines to produce an analog flow output signal in response to the PCM input signal.
