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.

The power of the media to draw the public attention to the particular issues and the problems is called as agenda-setting.
Agenda-setting list of issues that government officials and non-governmental people who are closely associated with government officials always pay serious attention to..be the center of attention. Setting an agenda is also very important politically, as the public agenda influences the political agenda. That is, candidates try to focus on issues that the public wants to hear. Agenda-setting theory suggests that media outlets shape the political debate by determining the most important issues and presenting them on news programs. The media has been described as the primary authority in choosing which news to report and prioritize based on what they believe people will be interested in.
