envelope delay n. Electrical Engineering (see quot. 1940).

ΚΠ

1940 Chambers's Techn. Dict. 301/1 Envelope delay, the time taken for the envelope of a signal to travel through a transmission system, without reference to the time taken by the individual components.

1943 F. E. Terman Radio Engineers' Handbk. v. 443 Envelope delay is of particular importance in tuned amplifiers handling television signals, because any variation in the envelope delay with modulating frequency adds to the total delay error of the system.

1956 S. W. Amos & D. C. Birkinshaw Television Engin. II. i. 20 A more sensitive indication of the seriousness of any phase distortion is given by the slope of the curve itself, usually measured by the slope of the tangent to the curve...
