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:
Hence correct option is b i.e 7.2 yuan.
Explanation:
Given data;
candy bar cost is $1
Nominal exchange rate = 6 yuan equal to 1 dollar
Real exchange rate is = 1.2 dollar per 6 yuan
Therefore price for one candy at china will be 
The price of candy bar at china is = 7.2 yuan
Hence correct option is b i.e 7.2 yuan.
Answer:The problem that was better defined was that of shortening the amount of tme students wait in the lunch line.
Explanation:
The second problem was not well defined because the school spirit can be increased in a vast number of ways which the class didn't mention any.
Therefore todefine the second problem, the class has to state a specified area in the which they want to tackle in other to incresa the spirit of the school just like the first class has specifically stated that it is the time student wait in lunch line they want to shorten.
A well defined problem will be more easier to solve than the one which is not defined.
The Endangered species act (ESA) authorizes two federal agencies to identify species as either threatened or endangered. For most marine species, that agency is the national marine fisheries service of (NOAA) or the National oceanic and atmospheric administration in the Us department of commerce
