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:
long term memory =Encoding, which is the ability to convert information into a knowledge structure.
Encoding, which is the ability to convert information into a knowledge structure.Storage, which is the ability to accumulate chunks of information.
Encoding, which is the ability to convert information into a knowledge structure.Storage, which is the ability to accumulate chunks of information.Retrieval, which is the ability to recall things we already know.
short term memory =limited capacity (only about 7 items can be stored at a time)
limited capacity (only about 7 items can be stored at a time)limited duration (storage is very fragile and information can be lost with distraction or passage of time)
limited capacity (only about 7 items can be stored at a time)limited duration (storage is very fragile and information can be lost with distraction or passage of time)encoding (primarily acoustic, even translating visual information into sounds).
Answer:
D. Both A and C.

C. A policy meaning 'openness' that allows people to express their opinions and vote.
Explanation:
Glasnost and Perestroika are words with Russian origin which respectively, mean openness and transparency, as well as restructuring. The word Glasnost, was coined to make court judgments and other judicial activities open to the public and journalists.
Perestroika is a term that means restructuring. The effect of promoting openness and transparency in the Soviet Union back then was an increase in freedom of speech for the populace as well as an increased transparency in government activities.
