An EDD test on a basic telephone channel indicated that an 1800-Hz carrier experienced the minimum absolute delay of 400 μs. Therefore, it is the reference frequency. Determine the maximum absolute envelope delay that any frequency within the 800-Hz to 2600-Hz range can experience.

The maximum envelope delay for a basic telephone channel is 1750 μs within the frequency range of 800 Hz to 2600 Hz. Therefore, the maximum envelope delay is 2150 μs (400 μs + 1750 μs).
