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:
D
Explanation:
Hope this helps :)) (also I took the test so ik its not B cause I got it wrong)
Uncertainty surrounded Lincoln's inauguration. ... Despite Lincoln's reassurances, southerners were not convinced. Many believed that slavery could not be protected in the current Union regardless of who was in charge. States that had already seceded continued to encourage border states to join their new nation.
