  1. If you take the time to READ the messages in this forum you will see that we are not allowed to post any attachments that break the copyrights laws. >:( >:(

    However, having said that, it is OK to post links to sites that have the books you want. I have a lot of books on microwave and antennas but have no idea were to up-load them for you to down-load.......




    Ok then, you can give me links if you dont wanna "break" the copyrights laws...
  2. Hi, I am very confused about this subject of attenuation. I have a circuit posted, and it is working at a center frequency of 25Mhz. And I need to calculate the attenuation at 2nd, 3rd, 4th and 5th harmonics of 25Mhz. From internet I found this formula:
    A(db) = -10 log(1+((w/wc)^2n)) where w is the desired freq. and wc is the center frequency, n is the number of elements (inductors and capacitors) in the circuit.

  3. Hello everybody, I will be doing a little research about PLC(programmable logic controllers) this summer, does anyone know any information about it? Or any books, sources? I especially don't know if PLC is %100 related with electronics? It seems more like a software engineers job to me. Any help on the subject would be greatly appreciated. Thanks

  4. Thanks but some of the pdf's cannot be opened. Acrobat gives error and says that "this file is damaged and couldn't be repaired." For instance I couldn't open gen.pdf. If you can replace these with the undamaged ones I would be grateful.Thank you.
