摘要
色同步信号是为了在接收端恢复与发送端被抑制掉的色副载波同频同相的载波而设置的。色同步信号在传输过程中的质量好坏,直接影响到彩色电视的接收效果,所以我们应对其有较深刻的了解,以便不断改善其传输质量。
Color synchronous signal is setup to resume subcarrier color signal as same frequency and phase in receive end,which is suppressed in send end.The synchronous quality in the course of transmitting color signal influences the reception of the color TV directly,so we should have a deeper knowledge of it so as to improve its transmitting quality constantly.
