Which of the following is not a key advantage of digital transmission? a. it is more efficient. b. it is simpler to integrate voice, video, and data on the same circuit. c. it is more secure. d. it permits only low transmission rates. e. it produces fewer errors

d. It permits only low transmission rates

Explanation:

According to my research on information technology, I can say that based on the information provided within the question one of the disadvantages of digital transmission is that is permits only low transmission rates. To send a voice signal as a bit stream one must send 8 bits, 8000 times per second, which corresponds to a bit rate of 64 kbps on digital transmission..

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
