What is the T1 and E1 output jitter when the T1 input jitter is 20 U.I. (T1 U.I. Units) and the T1 to T1 jitter attenuation
is 18 dB, for a given jittering frequency
Using the method mentioned above, the jitter attenuation can be calculated for all combinations of inputs and
outputs.
Because intrinsic jitter is always present, the jitter attenuation will appear to be lower for small input jitter signals
than for large ones. Consequently, accurate jitter transfer function measurements are usually made with large input
jitter signals (e.g., 75% of the specified maximum jitter tolerance).
