Sentence examples for modulation from inspiring English sources

The missing 413,000 peak, therefore, turns out not to be a problem after all, for it is one of the properties of frequency modulation that the wave doing the modulating does not, itself, ever show up as a separate peak in the signal.Dr Rial can thus tie all of the observed cycles directly to changes in the shape of the earth's orbit.

When a modulated electron convection current flows in an electric field of the same modulation frequency, the power transfer, P, between the field and the electron is given by where lc is the electron convection current and E is the electric field.

It is a modulation of twice the 413,000-year cycle a so-called "sub-harmony" of the main value.

In particular, two concepts may come into play: modulation and differentiation.

"Radio," which is generally understood to refer to the wireless transmission of signals by modulation of electromagnetic waves, came a decade later through the work of Fessenden and DeForest.The first microprocessors, or "computers on a chip," were developed at Texas Instruments and Intel, less than 40 years ago (in 1971).

Dr Rial therefore decided to try to work out what the oxygen record would look like if the 413,000-year cycle were imposed on the underlying 95,000-year cycle.One of the effects of frequency modulation is to create so-called sideband peaks in the signal.

But by reaching for the electronic-engineering textbook, Dr Rial has accounted not only for the notoriously missing peak but also for the extra peaks that are clustered around 100,000 years.Frequency modulation works by imposing the shape of a long-wave "signal" frequency on to a short-wave "carrier" frequency.

Incandescent light bulbs and fluorescent tubes are not really suitable for modulation, but they are yesterday's lighting technology.

The modulation occurs laterally, with no vertical motion whatsoever.

Even so, and despite Mr Robinson's energy and pugilistic credentials, the contest is probably as much of a mismatch as that between Hartlepool and Mr Mandelson, whose campaigning skills, complete with the occasional modulation of accent, are as formidable locally as they have proved nationally.Hartlepool is unlikely to hang New Labour's organ-grinder.

The main problem with radio-frequency amplifiers in receivers is the possibility of cross modulation that is, the mixing of two information channels, which can occur if an undesired modulated signal enters the radio-frequency input together with the desired signal.
