hangover delay

In communication system, a delay action which is generated by transmission line after control signal (such as sound signal) disappears. This delay action causes an echo suppressor to continue suppressing signal. The suppression time is proportional to delay of transmission line.; 在通信系統中,當控制信號(如聲音信號)消失以后，由傳輸線產生的延遲作用。回波抑制 器仍繼續對信號進行抑制,其時間與傳輸線的延遲成正比。
