The device may be triggered either automatically or manually depending on how the device is triggered , and it will also depend on whether the duty cycle is fixed or random.

设备有手动和自动两种触发方式，采用哪一种触发方式取决于设备是怎样被触发的，也取决于占空比是固定的还是随机的。

The device may be triggered either automatically or manually and depending on how the device is triggered will also depend on whether the duty cycle is fixed or random.

至于选择何种触发方式，还要依占空 比是固定的还是随意的来定。

The output of the FPGA is typically a waveform with a fixed-frequency, variable-duty cycle, which a counter and a digital comparator generate (Listing 1).

FPGA的输出是固定频率、计数器和数字比较器使占空比可变的典型波形(表1)。
