I'm sorry. I was cramming since i don't have enough time to create the project but i started to read now. :)

I researched about antennas. I read that the radius of the dipole rod affects the bandwidth but i don't seem to find the computations for the radius. The only thing the i found is an online calculator but the site didnt give the formula. :(

thank you for responding! Is there a way where i can combine the folded dipole antenna with another kind of antenna (except yagi-uda) so that i can make the antenna more efficient. (And if there's a way where i can make the antenna efficient with that height :( )

What i need are the ff: basic guidelines on how to create an outdoor antenna (you can send links :)) the most suitable type of antenna that can receive 70 MHz tv station frequency. The antenna will be mounted less that 3 m from the ground. computations that i need to know (you can also send...

Can someone enumerate the equipment needed in a microwave transmitter control room? i already searched the net and i somehow don’t understand anything haha. also can you please explain what each equipment does? thank you :)

Thank you very much! i was wondering why they multiplied 50 instead of multiplying it. hahaha

Homework Statement An antenna is modeled by a 40ohm resistor in parallel with a capacitor with Xc = -j25. The antenna is fed by a lossless 50ohm signal line 0.15 wavelengths long. Use a Smith Chart to find the input impedance to the transmission line.Homework Equations The Attempt at a Solution...

Thanks for your response! So i just need to convolve x(n) and h(n)? and the answer is y(n)? how will it become y(k) tho?

Homework Statement I have an impulse response h(n)=e^(0.1n)*[u(n)-u(n-8)] and an input x(n)={0,1,2,3,0}, how do I find the output y(k)? [/B]Homework EquationsThe Attempt at a Solution i don't even know how to solve. should i try convolution or should i substitute the values of x(n) in h(n)...
