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.
