beat frequency

This beat frequency can be thought of as an interference pattern in time.

Normally the beat frequency is associated with the lower sideband, the difference between the two.

Didn't anyone up there hear the beat frequency?

One function is for detecting the wing beat frequency of a mate.

The result is a heterodyne beat frequency that indicates the velocity difference.

Birds also have a variance in wing beat frequency.

A "heterodyne" is a beat frequency such as can be heard when two close musical notes are sounded together.

"Yes; the product of their phases is termed a beat frequency, Gregory.

Besides the beating frequency, the string also gives higher pitched natural overtones.

This produces a beat frequency which can be detected and used to determine the absolute difference between the lengths of the two arms.

But when both modems sing a note at the same time, the result is a recognizable chord or a harsh beat frequency sound.

By using sources of several wavelengths to generate sum and difference beat frequencies, absolute distance measurements become possible.

The followings table lists the beat frequencies between notes in an equal temperament octave.

In those with asynchronous flight muscles, wing beat frequency may exceed 1000 Hz.

Generally however, any non reciprocity in the propagation between the two beams leads to a beat frequency.

If is off by a small amount, then the beat frequency is not exactly , which can lead to the speech distortion mentioned earlier.

"Beat frequencies on the sixth, ninth, and twelfth harmonics, dominant.

Two tones close in frequency generate a beat frequency at the difference of the frequencies, which is generally subsonic.

The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies.

The difference between consonance and dissonance is not clearly defined, but the higher the beat frequency, the more likely the interval to be dissonant.

Even with the compensation of larger wings per unit body mass, larger birds also have a slower wing beat frequency.

These are the beat frequencies.

When these stops are played together, a unique undulating effect results due to alternating constructive and destructive interference (beat frequency).

This beat frequency, detectable with a photodiode, is the carrier-envelope offset frequency.

As insect body mass increases, wing area increases and wing beat frequency decreases.
