The difference between the highest and lowest frequencies in a band or collection of frequencies is known as the bandwidth. The bandwidth in a standard North American telephone circuit is 64 Kbps. The amplitude or height of the wave is altered by amplitude modulation.
<h3>
What do you mean by Telephone Circuits?</h3>
The standard line found in telephone circuits is this one. The frequency response of such a line resembles that of a low-pass RC filter. The telephone line loss and consequently the low-pass filter action increase in frequency as a result of the wires' increasing resistance, which causes an increase in I2R wire losses. 14 The frequency response of a 1 km-long, twisted line is reduced by 9 dB at 1 MHz and keeps going down for higher frequencies, Let's suppose that a straightforward, 1 km-long transmission system is required. A pair of 1 km long twisted copper wires may transmit data with a loss of less than 9 dB.

Answer:
Atmospheric pressure decreases as increase of altitude occurs
Explanation:
gravity has less of an effect the further you travel from the center of the world. This means more molecules of atmosphere are closer to the earth's surface at lower altitudes. Thank Jesus for a healthy atmosphere!
Answer: Two declarations throughout history protect the rights of the child.
Explanation:
The first was passed in 1959, which was guaranteed by the United Nations Assembly. It was the first document guaranteeing the rights of the child. The second declaration was adopted in 1989 again at the United Nations Assembly. The second declaration makes more detailed provisions on the rights of the child and contains over 50 articles. Some of the basic points are the right to life of the child, equal rights for all, the right to care, the right to freedom of expression and opinion, the right to privacy.
The correct answer is the Fiedler’s contingency theory. This
is a type of contingency theory by which it shows or focuses on the
effectiveness of leadership that are likely to base on a particular situation and
the numerous factors that may take place.
