In Matlab there is a toolbox that can help. If you have matlab type fdatool from the command prompt and see if the filter design and analysis toolbox opens.
Re: Why use VCO?
Well I can give one example for you ... you have to understand mixing and intermediate frequencies to get it:
I've just worked on a project where we used a magnetron as a source. The frequency drifts with temperature changes. The source is mixed a few times and filtered (A...
Re: begining RF
If you are already familiar with electromagnetics, then the book mentioned above by Pozar is good. If not, get an electromagnetics book to start with. If you have a strong physics background start with an electrodynamics book.
At best, power into the transformer is equal to the power out. So V1*I1 on the primary equals V2*I2 on the secondary. So V1*I1 = V2*I2, and if you re arrange that you get I1/I2 = V2/V1. The transformer works through magnetics, and you can see from above that the currents and voltages are...
Re: Pls explain the usage of Infinite While/For loop in Firm
I've answered this question in another thread, but here goes:
When you reach the end of your code processing, the Instruction pointer will keep incrementing and executing code. Suppose I used 45k of 64k in the chip. When I hit the...
Re: interview question
This looks like a monostable multivibrator? Here's a quote from wiki on multivibrators:
"When triggered by an input pulse, a monostable multivibrator will switch to its unstable position for a period of time, and then return to its stable state. If repeated application...
I'm gonna have to guess no. Not all light incident on the mirror will be reflected. Some of the light will be used to heat up the mirrors. So I'd say the light will slowly fade and you'll end up with a room full of warm mirrors.
Am I right ? I dunno ...
My suggestion is:
Get a small easy project to do and build it.
Start asking yourself why things are done the way you saw, and how the things work.
This question may lead to intense physics and math, so get some math and physics fundamentals books.
