Can someone explain to me what is the wavelength of body heat?
Since visible light is between 400nm - 700nm. Is body heat wavelength above 700nm?
What is the wavelength range of body heat in respects to nm or m?
And lastly are Infrared cameras made with Avalanche Photo Diodes? like the one...
I have a circuit (attached) that is providing too much voltage into my FPGA. I attached the circuit.
The output of the transimpedance amp is sending 4.2V to my FPGA which only needs 3V. I h ave reason to believe that the 4.2V input into the FPGA is causing some weird anomalies to occur while...
reflection coefficient gamma = ZL-Z0/ZL+Z0.
My question is can you calculate the reflection coefficients when ZL has a real and imaginary?Lets say that Z0=50 ohms and ZL = 125 +j40.
All my example in books show ZL and Z0 being real only. Well how do you determine reflection coefficients...
Since I lack the understand of real world applications of Fourier Transform in the real world I decided to buy a signals and systems book (Lathi) do some Fourier Transform problems and them do the same problem in Matlab.
The question in the book wants me to find the Fourier Transform of...
Again, thanks for taking the time to help me out. It is much appreciated!
Ok I think I know what I was thinking wrongly about...feel free to comment where needed.
If the dipole is positioned vertically (y axis), on the directivity plot the radiation pattern of the E-field would be in the...
To be honest I am still confused. No fault of your own. Here is the reason.
Figure 19 says that if the dipole is horizontal then the E field is horizontal.
Figure 19 says that if the dipole is vertical then the E field is vertical.
Figure 13 shows a horizontal dipole but I see a a...
Could you please help me to understand some basic concepts about antenna polarization. The books I have are really confusing and do not have examples that I can learn from.
Please look at the attached E plane radiation pattern image I attached (figure 13).
The books image (figure 13)...
My question is two fold.
1) I was asked to measure the BW of a LNA (RF2472G). Is this done with a VNA. I have an obsolete model in my lab Agilent/HP 8720ES.
2) Exactly how would you measure the BW of the LNA in general? Using the VNA? Is this a S11, S12, S22, S21 parameter? please help.
When you say that "one uses mu metal at low frequencies" I assume you are talking about an inductor core made of mumetal powered by a low frequency power supply?
Would 60Hz Ac be considered a low frequency power supply?
Not to be a pain but I read a post from the Physics forum
( https://www.physicsforums.com/archive/index.php/t-12250.html) that suggest that
"Static electricity" can really only be defined one way: "charges that are not moving."
So I thought that Static Magnetic fields implied...
If the magnetic field is static then that means it does't move. So if it doesn't move that means that it can't pass through the cage correct? Or does static just mean slow moving?
I have a question regarding Faraday Cages...
Faraday Cages blocks static electrical fields
I read somewhere that static magnetic fields can penetrate the faraday cage when changed slowly. Faster changes in static magnetic fields cannot penetrate a faraday cage, is this true?
Also does...
