Answer:

The correct option is;

Technology is not able to keep up with the demand for innovative ideas

Explanation:

The present day problems of engineering and society are mostly occurring for their first time ever or in this period and as such are complex with regard to the current state of technology and know how. For example, the problem of human induced climate change as never been faced anytime in the past history of engineering and mankind as a whole. The capacity to communicate and generate data at the current level has never been reached. The world has never the current number of individuals needing the basic necessities of life.

As such, the engineer in the competitive global job market is more than ever required to produce innovative solutions to problems rather than implement current technologies.

natima [27]

Answer:

Fire/Flame resistant clothing and aprons

Explanation:

Individuals working with or around welding equipment are usually required to wear Fire/Flame resistant clothing and aprons which are designed to protect the user from various types of hazards including heat, fires , burns , and sometimes radiation. In this scenario, it would protect the individual from the welding sparks that are produced when welding, which tends to fly all over the place and can catch fire in some cases. These clothes will prevent that from happening.

The output S/N at thereceiver must be greater than 40 dB. The audio signal has zero mean, maximum amplitude of 1, power of ½ Wan
abruzzese [7]

Given that,

The output signal at the receiver must be greater than 40 dB.

Maximum amplitude = 1

Bandwidth = 15 kHz

The power spectral density of white noise is

\dfrac{N}{2}=10^{-10}\ W/Hz

Power loss in channel= 50 dB

Suppose, Using DSB modulation

We need to calculate the power required

Using formula of power

P_{L}_{dB}=10\log(P_{L})

Put the value into the formula

50=10\log(P_{L})

P_{L}=10^{5}\ W

For DSB modulation,

Figure of merit = 1

We need to calculate the input signal

Using formula of FOM

FOM=\dfrac{\dfrac{S_{o}}{N_{o}}}{\dfrac{S_{i}}{N_{i}}}

1=\dfrac{\dfrac{S_{o}}{N_{o}}}{\dfrac{S_{i}}{N_{i}}}

\dfrac{S_{i}}{N_{i}W}=\dfrac{S_{o}}{N_{o}}

Put the value into the formula

\dfrac{S_{i}}{2\times10^{-10}\times15\times10^{3}}

\dfrac{S_{i}}{30\times10^{-7}}

S_{i}

S_{i}=30\times10^{-3}

We need to calculate the transmit power

Using formula of power transmit

S_{i}=\dfrac{P_{t}}{P_{L}}

P_{t}=S_{i}\times P_{L}

Put the value into the formula

P_{t}=30\times10^{-3}\times10^{5}

P_{t}=3\ kW

We need to calculate the needed bandwidth

Using formula of bandwidth for DSB modulation

bandwidth=2W

Put the value into the formula

bandwidth =2\times15

bandwidth = 30\ kHz

Hence, The transmit power is 3 kW.

The needed bandwidth is 30 kHz.
