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.

Answer:
The number of years they serve per term.
The most significant immediate impact of the Columbian exchange was the cultural exchanges and the transfer of people (both free and enslaved) between continents.
Answer: food desert
Explanation: Food desert which is the direct opposite of food oasis is an area with decreased or limited access to affordable healthy food i.e decreased access to food and availability of healthy food.
Food desert is a good example of institutionalized bias in food system that have a negative impact on health of people living in such areas. Many groups that have entered the US have experienced this form of discrimination in one form or the other.
