How do you calculate the power of white noise?
To calculate the power of white noise, you can use the formula for power, which is the mean of the squared values of the signal. For a white noise signal represented as ( x(t) ), the power ( P ) can be calculated using ( P = \frac{1}{T} \int_0^T x^2(t) dt ), where ( T ) is the duration of the observation. Since white noise has a constant power spectral density, its power is generally equal to the variance of the noise signal. In discrete terms, if you have a sample of white noise, the power can be approximated as the average of the squared samples.
Why do we use current sources as load in differential amplifiers?
Current sources are used as loads in differential amplifiers to improve their performance by providing high output impedance, which enhances the gain of the amplifier. They also help in maintaining a constant current through the differential pair, ensuring better linearity and increased common-mode rejection ratio (CMRR). This results in improved signal integrity and noise immunity, making differential amplifiers more effective for applications requiring precise signal amplification.
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.
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.

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~
Peak-to-valley ratio in HPLC?
The peak-to-valley ratio in high-performance liquid chromatography (HPLC) is a measure of the separation between the highest peak and the adjacent valleys in a chromatogram. It is calculated by dividing the peak height by the lowest valley height around the peak. A higher peak-to-valley ratio indicates better resolution and a more efficient separation of analytes.
How do you get a good FT-IR baseline?
To get a good FT-IR baseline, ensure that the instrument is properly calibrated, the sample chamber is clean, and measurement conditions are consistent. Use a blank solvent or reference material to correct for any background noise, and average multiple scans to improve signal-to-noise ratio.
What are the technique in reducing of noise in FM?
To reduce noise in Frequency Modulation (FM) signals, techniques such as pre-emphasis and de-emphasis can be employed. Pre-emphasis boosts higher frequencies before transmission, while de-emphasis reduces them at the receiver, improving the signal-to-noise ratio. Additionally, the use of limiters can help eliminate amplitude variations caused by noise, ensuring that only the frequency variations are decoded. Finally, implementing digital signal processing techniques, such as filtering and error correction algorithms, can further enhance noise reduction in FM systems.
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".
