What equipment do engineers use?
electric vibrator!
Do civil engineers use jack hammers?
Civil engineers do use jackhammers to break-up old roads and put down new ones.
Where the phased locked loop is used?
Phase lock loop is used in analog and digital communications to keep the phase of the output signal the same as the input signal.
What is use of engineering drawing in various fields?
Engineering Drawing is a two dimensional representation of three dimensional object.It is graphic language from which a trained person can visualize the object.It is an universal language of engineers by which you can represent your new ideas. Mechanical Engineers use E.D to draw Auto mobiles,Machine Designs and Components etc. Civil people use the same E.D for representing the designs of structures,dams,bridges,building etc. Electrical and Electronics engineers use it for drawing circuits,electronic components,fabrication works, satellite designs,Antenna for signal recieving etc.
What type of tools do robotic engineers use?

Peak-to-valley ratio in HPLC?
to calculate signal to noise use this formulae peak hight *2/noise level
Examples of solved problem on signal to noise ratio?
i have no idea but you guys could possibly use this formula SNR=10log and in the base 10 or SNR=avg signal/avg noise
How do you replace Nissan Quest Signal switch?
When I use the signal it makes lot of noise
How are logarithms used in electrical engineering?
Electrical engineers use logarithms to work on signal Decay.
What are the two primary transmission parameters engineers use when designing a circuit?
Signal Loss and Bandwidth
If a binary signal is sent over a 3-kHz channel whose signal-to-niose ration is 20dB what is the maximum achievable data rate?
The Nyquist Limit can be disregarded as this is not a noiseless channel (faster signal = more noise, this channel's s/n ratio is provided as 20dB)thus we use Shannon's result which says the maximum data rate of a noisy channel is X = H Log2 (1 + S/N) bps using 10Log10 S/N as our standard quality2 = Log10 S/N --> S/N = 102 --> S/N = 100X = 3000 Log2 (1 + 100) bps which gives you x = 19,974.63bps as your final answer.~ Mike------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ALTERNATIVE APPROACHThe formula -Shannon Capacity = Bandwidth * log2 ( 1 + Signal Power / Noise Power )gets approximated to -Shannon Capacity = Bandwidth * ( Signal to Noise ratio in dB ) / 3assuming the fact that ....Signal to Noise ratio in dB = 10 log10 ( Signal Power /Noise Power )and also assuming1 is much much less than Signal Power/Noise PowerSo in the present case the approximate answer works out toShannon Capacity = Bandwidth * ( Signal to Noise ratio in dB ) / 3 ...= 3KHz * 20 dB / 3= 3 * 103 * 20 / 3 bits per second= 20000 bits per second~ANIRUDDHA GHOSHJADAVPUR UNIVERSITYBSc Mathematics - 2004 - 2010MCA - 2007 - 2010~
Are there wireless noise canceling headphones that use white noise and not music?
Noise canceling headphones use neither white noise nor music. True noise canceling headphones use microphones that pick up outside sounds, amplifiers to invert those sounds, and combining circuits to combine the signal to be played with this inverted external sounds before feeding it to the speakers. The external noise vanishes by cancellation, which is why they are called "noise canceling".
How would one use a hp signal generator?
Hp signal generator serves as a wireless broadcaster. The engineers designed this instrument. It was designed to be used in RF applications exclusively 50 omega loads.
Is it possible to use low frequency noise to determine if there is someone listening in on a radio transmission?
No. It is not possible to determine if someone is listening in on a radio transmission, with or without noise. The only protection you have is to scramble the signal.
What is the clicking noise you hear coming from a railroad signal bungalow?
Relays. Most RR signals still use relay technology.
Why Positive Feedback can't use in Amplifier?
because +feedback amplify noise also.it amplify the noise to input ratio by[1/(1-G.H)]. WHERE g=open loop gain H=feedback gain
What characteristic of Digital Subscriber Line transmissions results in greater noise and signal loss than occurs in conventional transmissions?
They use higher frequencies
