Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.
The problem of suppressing multipath interference in television reception motivated Clarence Hansell of RCA to use delay lines in his 1939 patent application. He used "delay cables" for this, relatively short pieces of coaxial cable used as delay lines, but he recognized the possibility of using magnetostrictive or piezoelectric delay lines. [7]
Many US radio talk shows use broadcast delay to avoid FCC penalties. In radio and television, broadcast delay is an intentional delay when broadcasting live material, technically referred to as a deferred live. Such a delay may be to prevent mistakes or unacceptable content from being broadcast.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
Delayed auditory feedback can be constructed using a speaker pointed at the person speaking, yielding a "speechjammer". [10] With an individual who does not stutter, auditory feedback speech sounds are directed to the inner ear with a 0.001 second delay. [11] In delayed auditory feedback, the delay is artificially disrupted.
Delay RMDs by stashing money in a 401(k) — and keep working. ... the IRS allows you to use a different formula to calculate your RMDs which can ease your household’s tax burden.
A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...
On the other hand, you can delay Social Security beyond your FRA to gain an extra 2/3 of 1% per month until you turn 70, which is the age when you'll qualify for your largest possible checks. If ...
