A digital communication system is operated at 30 dB SNR. Answer the following:
(a) If the required Shannon’s capacity for the communication system needs to be
maintained at 10 Mbps, determine the value of allocated bandwidth. [3]
(b) If the sufficient bandwidth calculated in 3a is not available, what needs to be done
so that same Shannon’s capacity is maintained.
Answer:
(a) 1.003 MHz
(b) increase the signal-to-noise ratio
Explanation:
The relationship between channel capacity, bandwidth, and signal-to-noise ratio was described by Claude Shannon in the 1940s, based on previous work by Harry Nyquist and Ralph Hartley. The relationship is given by the formula ...
C = Blog₂(1 +S/N)
where C is the channel capacity (bits per second), B is the bandwidth (Hz), and S/N is the signal to noise power ratio.
__
(a)You want to find B for C=10^7 and 10·log(S/N) = 30. Solving for B, we find ...
B = C/log₂(1 +S/N)
B = 10^7/log₂(1 +10^(30/10)) = 10^7/log₂(1001) ≈ 1.003 MHz
The allocated bandwidth must be at least 1.003 MHz.
__
(b)Shannon's relation tells us the alternative to increasing bandwidth is increasing signal-to-noise ratio. If "sufficient" bandwidth is not available, the signal-to-noise ratio must be increased.

Explain why the scenario below is a good example of an engineer using creative thinking. Situation: Connor has been working on a device that can transfer data from an iPod to a PC by simply pressing the screens together. The technology exists between devices of the same brand, but it does not cross over to all computerized devices. He has built several devices and each time is able to add another group of devices to his scenario. He has kept a journal with all of his successes and all of his failures, as well as any new ideas he has had along the way.
Answer: Conner has strong creative thinking skills
Explanation: Conner has been able to easily record his process in a journal that will help him later on in keeping track, and knowing what things work and what things to steer clear of attempting again. His ability to use creative thinking has lead him to build multiple devices that draw him closer to a better final outcome.

steering wheel pull, make sure that symptoms are not caused by problems.
(A) steering
(B) suspension
(C) front wheel alignment
(D) All of the above.
In steering assembly such as vibration, abnormal tread wear, or steering wheel pull, make sure that symptoms are not caused by front wheel alignment.
What leads to steering wheel vibration?Most times, the turbulence in the road or any kind of rough driving, and other factors can bring this kind of issues with alignment. This can cause one or more of the wheels of a car to come to a state of rest at a skewed angle and thus it can lead to steering wheel shaking or vibrations.
The act of Ignoring steering wheel vibrations can bring about other issues that can lead to a more larger problems for your car and thus it is better to handle or repair it.

What two variables are multiplied together to calculate weight? (Taking a quiz rn for tech)
The weight of an object is the force of attraction that the object has to the Earth. It is the product of the mass of the object, multiplied by the acceleration due to gravity. You may choose to calculate the weight of an object to solve a physics problem
The two variable that are multiplied to calculate for weight are mass(m) and acceleration due to gravity(g)
weight is the measure of the force of gravity acting on a body. In other words weight is describe as the force of gravity acting on a body.
Weight is a vector quantity. This means it has both magnitude and direction. The SI unit for weight is Newton.
Therefore, weight can be calculated as the product of mass of the body and the acceleration due to gravity. This can be represented mathematically as follows:
F = mgwhere
m = mass
g = gravity = 9.8 m/s²
