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.

Seawalls stabilize beaches producing renewed deposition on the beach. true or false
victus00 [196]

The correct answer is: "True".

Erosion is the continuous deposition of land. The coast is constantly exposed to erosion by the sea. Besides protecting areas for human habitation, seawalls help protect the coastline from erosion. However, they receive all of the force from the sea. This does affect its structure and will eventually need constant maintenance throughout time. This normally leads to high costs involving these activities.

Asch demonstrated that group unanimity exerted an influence on conformity, above group size alone.​ question 1 options: ​true. ​
Lorico [155]

The statement is TRUE.

In 1951 Solomon Asch carried out the famous Conformity Experiments, set out to <u>measure the dynamics of group-thinking</u>. He presented his subjects with an extremely simple judgement task with a very obvious answer, joined by a previously prepared group that was told to answer incorrectly on purpose. By making it so simple, it would be clear that any subject that answered incorrectly would be doing it because of group pressure. With this first experiment, <u>Asch proved a correlation between  a group's influence on an individual's conformity</u>.

Further trials went deeper into which factors were the most impactful to influence conformity. The results showed that <u>increasing group size</u> by up to three times, <u>raised the conformity levels to 32%</u>. However, larger groups did not impact this number. Applying group unanimity, on the other hand, showed an increase of as much as 80% on the conformity rates.

This clarified how much bigger of an influence unanimity was over group size, meaning it mattered more to an individual if an entire group agreed on something (even if the group was small), over a larger majority's opinion when a group was more split-up.


Hope this helps!
