Fessenden felt that, ultimately, a continuous-wave transmitter-one that produced a pure sine-wave signal on a single frequency-would be far more efficient, particularly because it could be used for quality audio transmissions.

As a theme experience, Pokemon Island is pure signal, zero noise.

The electrical activity from eye movements, facial muscles, respiration, and the heart's electrical limits the effectiveness of bedside EEGs for routine use in the ICU, but under neuromuscular blockade, these artifacts are minimized and a relatively pure signal is obtained.

A 'pure' signal in the form of a perfect sine-wave contains only one frequency, the fundamental and no multiples of it (harmonics).

It is possible to make a doppler radar without any pulsing, known as a continuous-wave radar (CW radar), by sending out a very pure signal of a known frequency.

It also featured discrete circuit construction, no integrated circuits were incorporated in order to keep the signal pure.

Asian Mussolinis will snicker at our sweet disorder as we lust after the way to deliver a pure signal along with a piping-hot pizza.

Still, it would take Jimi Hendrix to completely reimagine the electric guitar as a source of pure electronic signals: controlled or chaotic, abstract or as visceral as the blues.

I call it contamination, but of course this pollution is actually pure signal to the researchers who study these sources of light.

Because the NES and Game Boy tend to be noiser, modifications were made to both to help provide a more pure recordable signal.
