annular ring antenna
I'd like to design an annular ring slot antenna for 2.4 GHz. Could someone kindly point me out in the right direction as to how to design one (inner and outer radius specification etc) for a given substrate of dielectric constant er and thickness.
I have tried to...
PDE is type of heat equation.
Where have above reference notes?
Many book only gives an example of solving heat equation using fourier transform.
An exercise asks me to solve it for using fourier and laplace transform:
In the heat equation, we'd take the fourier transform with respect to x...
Please look at the circuit
How can I use HIGH/ LOW to control the MOSFET to ON/OFF??
1)If Gate >5V.........the path between drain and source = close circuit
the load is come to vdd
2)If Gate =0V.........the path between drain and source = open circuit
How about 2- bit full adder??
I can nit find in the powerpoint attached file
Because I found that the S0 S1 and carry is very complex
I found S0 is similar to 1 bit full adder....I also is A0 XOR B0 XOR Cin
but S1 is very complex
Any one can help....thank
I knew that the IC has a zero code error,the data sheet is said about 0.5mVpp
but, I had an error over then 2mV
Besides,the reference gound is common with the all circuity ground
How to solve it~~~Please~~~
I am used a AD5678 -2 (16 bit 2.5V internal Ref) DAC
**broken link removed**
When I put all 0 in the DAC...It still occurs 0.002V
How can I reduce the output noise and solve the zero code error???
Please give a...
