I believe its the 3rd one
Explanation:
hope it's right!
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.

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 appropriate response is average daily balance method. This is a typical bookkeeping technique where Visa intrigue charges are computed utilizing the aggregate sum due on a card toward the finish of every day. The normal day by day adjusts adds up to every day's adjust for the charging cycle and partitions by the aggregate number of days in the charging cycle.
because both Spain and Portugal established colonial empires during the 15th century
Answer and Explanation:
The Supreme Court concluded that the plaintiffs (black children) have been denied their rights because, by segregating them from white children, the state laws that legitimized such segregation and established different public schools for white and black children, contravenes the Fourteenth Amendment which guarantees equality and equal protection of the law.
