解调系统(一)组成解调系统由选通脉冲发生器、奇偶数脉冲分离器和话路解调器三部分组成,其方框图如图5所示.选通脉冲发生器的作用是供给各路选通脉冲及产生二组96千赫辅助脉冲(一组96千赫奇数,一组96千赫偶数),分别如图6(g)、6(c)和6(d)所示.自接收机来的视频脉冲(图6a)经阴极输出器送至同步脉冲检出器,同步脉冲检出器将同步脉冲检出,用它去控制 Demodulation system (A) The composition of the demodulation system consists of strobe pulse generator, the odd and even pulse separator and channel demodulator composed of three parts, the block diagram shown in Figure 5. Strobe generator role is to provide Way strobes and generate two sets of 96 kHz auxiliary pulses (one set of 96 kHz odd numbers and one set of 96 kHz even numbers) as shown in Figure 6 (g), 6 (c), and 6 (d) The video pulse from the receiver (Figure 6a) is sent to the sync pulse detector via the cathode output and the sync pulse detector detects the sync pulse and uses it to control
