Fm radio
Tropospheric propagation.
when the signal encounters a rise in temperature in the atmosphere
instead of the normal decrease (known as a temperature inversion),
the higher refractive index of the atmosphere there will cause the
signal to be ben

Since it is not limited by the curvature of the Earth
Cellular telephones
Line-of-sight propagation
at higher frequencies and in lower levels of the atmosphere,
neither of these effects are significant. Thus any obstruction
between the transmitting antenna and the receiving antenna will
block the signal, just like the light that the eye may sense.
Therefore, since the ability to visually see a transmitting antenna
(disregarding the limitations of the eye's resolution) roughly
corresponds to the ability to receive a radio signal from it, the
propagation characteristic of high-frequency radio is called
"line-of-sight"

3.what is the "state" of a running program (or process)? Be specific. Why must the state of the current program be saved prior to processing an exception or interrupt? Explain. Which parts of a program's state are saved through the processor's exception-processing mechanism, and which parts are saved by the exception handler or interrupt-service routine? assembly. 68000

State whether the data described below are discrete or continuous, and explain why. The numbers of typos in different students' essays. Choose the correct answer below. A. The data are continuous because the data can only take on specific values. B. The data are continuous because the data can take on any value in an interval. C. The data are discrete because the data can only take on specific values D. The data are discrete because the data can take on any value in an interval.
