9.1 时间测量电视技术中需要的主要时间测量有a: 边沿上升时间,b:包括脉冲持续时间的波形定时,c:信号通过线路与仪器的传输时间。在这些测定中,务必遵守一定惯例使得所得结果具有标准的形式。例如,边沿上升
9.1 Time Measurement The main time measurements required in television technology are a: rising edge time, b: waveform timing including pulse duration, and c: transmission time of the signal through the line and instrument. In these tests, it is important to follow certain conventions so that the results obtained are in the standard form. For example, the edge rises
