@famousken. I'm not familiar with analog multiplexers. Perhaps you could elaborate?
@Averagesupernova. Interesting. I shall try it with the optocouplers first. Thanks!
Thanks, supernova. Do you have any circuit diagrams of your PWM design?
I figure that since my idea is already some idle musing, I might as well put some more effort into it. I'm considering a stereo implementation using IQ modulation, and I'm also reading up on AGC gain control circuitry for...
Well, for starters, it's not an "exercise." It's just some idle musing on my part.
I'm trying to go building to building and maybe extend the implementation to go about a mile. Purpose? Just for fun.
IR is a method, but the issue of modulation (and the stuff I listed previously) are still important. Will digitizing the signal and then using IQ modulation work/be realistic in terms of my design objectives?
Ah, Averagesupernova, that's a good approach. Now I have something to do over the weekend. Haha.
PWM through a comparator is still a one-channel modulation, albeit a better approach than my original AM modulation. Is there any way we can extend that to two channels?
I think I did a similar problem with a rollercoaster. Basically, 1 and 2 must intersect and 3 and 4 must intersect at their respective points. The value of their first derivatives must be the same because it must be continuous, and the value of their second derivatives must be the same for them...
The average speed for the entire trip is the weighted average of the speeds of jogging and driving. Set that up as an equation:
(9.5*8+x*16)/24=22
x = 28.25 km/h
The nullity of a vector space is also known as the dimension of the nullspace, a fundamental subspace whose dimensions are defined by the rank of the nullspace basis. An easy way to compute the nullity is to subtract the number of pivots from the number of columns.
This could be a lemma in...
There are many ways to calculate inverses. Your definition follows with the computation of the inverse of A by doing row operations to [A|I] until it becomes [I|A^-1] (assuming that A is invertible). Another way of calculating inverses is by dividing the cofactor matrix of A transpose by its...
Standard audio CDs do 44KHz/higher rates. Is it naive of me to think that it can be done cheaply at a reasonably higher quality?
Free space optical comms., as I understand it, use really bright LEDs, or in the case of IrDA, infrared beams. Are there any existing laser implementations of FSO...
Typically, college physics sequences have them one after the other. It all boils down to how much you're willing to work. I took both Mechanics and E&M (the AP course offered in high school) concurrently and placed out of those two classes, but as with what physics girl phd said, I had to teach...
I am not quite sure what you're asking, but it seems like it's analogous to taking the substring of a String and then using indexOf() to find the first index of that String (applied to Arrays in this case).
Perhaps if you defined what "all n2 elements of a2" mean, we'd be able to help you.
