as far as i know typical fm is in MHZ ( 87 - 105 or something don't know exactly). So, 909.5Mhz on radio seems wrong. are you sure its not 90.9 Mhz. AM works in hundreds kilo hertz range
in any case: 909.5Mhz => 909.5 x 10^6
Mega: 10^6 kilo: 10^3
hope this helps,

sin(x)/x is called sinc x. Its different than sine. Sinc(x) is most important function in communication systems and filters. because theoretical impulse response for "best" filter is a sinc.
So for each material there is e-field strength (in coulumbs) my EM textbook had this. As for the rule, you can use any rule to find the E-field between two objects. Most common is coulumbs law. This is all theoretical, practically this won't work because there is tiny bit of charge everywhere...
convolution definition is incorrect. It should be integral of G(t-tau)epsilon(tau) dtau.
You can't integrate over depsilon. If epsilon is a function. It means nothing. So, try with proper definition.
Your use of convolution property is correct, so it should work out. If not then try first...
Good place to start would be for you to look for kinematics equations. (Google it you will find tonnes of reference).
You are solving this in 2-D. So, you would just break kinematics equation in two component x and y. high school physics textbook may be good for that if you can get hold of it...
I have used Oppenheim in my first signals and systems course. I would say it wasn't too bad. I esp. liked the problems (it contains tonnes of them). First course in signals and systems is somewhat challenging so it would take some effort to get through the book on your own. But more courses you...
Hey,
My answer:
1. spark is caused due to electric field breakdown. i.e. every material (such as air) has E-field strength. If E applied is more than this strength. The material breaksdown and material would act as conduct till the E-applied is short. Good example of it is lightning. You can...
I don't watch football. So I have no idea what the terms mean. But I think question is asking whether ball will be able to travel 120 ft. or not. which according to your calculation it would. (May be i am wrong i don't know)
The first equation comes from centripetal force which you already figured out.
The second equation is the equation to keep The Car from moving in the air.
So, consider a box on floor => for that you would do N = mg
In this case. N = mgcostheta. because you don't want car to fly from the...
I remember this question from my gr.7 class and I remember writing like huge essay to explain it. Let's see if i can do it in few lines. So, you have 100 rooms. or essentially 100 numbers. Then think about factors of each number. So let's say 8 for example factors are: 1, 2, 4, 8.
Now think...
Gauss' law works due to symmetry. If the surface is not symmetric, such as 10x10 plate; then you don't know the direction of the electric field so it wouldn't work. (Unless you can use the approximation that distance is very small).
If the surface was infinite plane you know the direction of...
My suggestion for this kind of circuit is using source transformation to simplify the circuit and then use thevenin theorem, makes life much easier and it is very very fast.
Do the following for source transformation:
i) you can take 12V source and 6K resistor in series with source and...
I guess it depends on the the type of surface. But berkeman is right only net flux is zero. However, depending on surface you could conclude sometimes that E is zero. example, if the surface is sphere. than gauss law says Q = 1/epsilon(surface int.) of Edot ds. If it is a surface integral over...
