DELAY LINE

1. A transmission line , or equivalent device, used to delay a signal . ( 188 ) 2. A single- input - channel device, such as a single-input sequential logic element , in which the output channel state at a given instant, t, is the same as the input channel state at the instant t-n , where n is a number of time units, i.e. , the input sequence undergoes a delay of n time units, such as n femtoseconds, nanoseconds, or microseconds. Note: The delay line may have additional taps yielding output channels with values less than n . ( 188 )
