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.

Maria is in at the exploration stage of the career development cycle.
<u>Explanation:
</u>
The exploration career stage is the first stage before employment where the individual just graduated college and ready to join the work environment. The individual also narrows down their preferences influenced by parents, friends and teachers to get a right career path.
There is also a tendency to have expectations that may be unrealistic, creating fantasies about the place of employment, work or work environment before being employed. For most people, the exploration stage is at mid-twenties while for some it might come late or earlier.
Answer:
D
Explanation:
It was the golden age for African artisits, musicans, and writiers. It also set the stage for the civil rights movement so a b and c wouldn´t make sense as an answer
Answer: B
Explanation: All of them are correct, but this is the most logic answer
