This signal produces a black-and-white picture on a standard monochrome receiver.

Weak signals combined with uncertain developments can produce the appropriate climate for structural change.

The combined signals of the four-part array produce a correlated image which is used for deep space study.

How does your television decode the signals to produce the picture?

But two signals passing through amplifiers produce some intermodulation products.

For most people, these spontaneous signals may produce nothing more than a song that is hard to get out of the head.

"But it is, I believe, a signal at least to produce vaccine to hold in readiness."

A signal appearing in the twelve o'clock sector of the vision field (at the top) will produce the fastest reaction.

The resulting two signals can possibly produce a pleasing stereo effect.
