The GSM-900 (900MHz band) link budget allows a maximum isotropic path loss of 143 dB (the antenna gains are not included). Which is the corresponding maximum cell radius for undistributed free space propagation?

I need help with this exercise, I don't even know where to start. imgur(dot)com/WDCikKK(dot)png

Hi, I need to to the following exercise: Estimate the measured rise time when connecting a 10kHz square signal, with an output impedance of 1 kΩ, to the oscilloscope using a coaxial cable. I know that Rise time = 0.35/BW, but I don't know how can I find t...

I got to do one last exercise: From the specifications of the function generator calculate the standard uncertainty of the amplitude of a 1 V (peak) sinusoidal signal of 1 kHz. The specifications say that: Accuracy at 1kHz = +/- 1% of the specified output...

man command or command -h I guess you are talking about linux commands

Yeah you won't be able to reproduce that on a Mac, since Mac runs OSX and you need to do the exercise on Windows. You better get a virtual machine or borrow a friend's computer.

Check google LOL, all that is explained, for the purpose of netstat and the -a switch just look for manual page netsat, or man netstat if you are running on Unix.

That is all the information there is, there is no V, Current or phase shift, just whats on the photo... u.u

Thanks!

And then it continues: Calculate the standard uncertainty of the oscilloscope when measuring the amplitude and rms value of the previous signal. Take into account the oscilloscope noise. I have been looking through the entire Oscilloscope's documentation...

I think something is wrong with your exercise, there is no a and b that match |3a| = 24 cm, |2b| = 10 that can get |3a-2b| = 20 . Check image. imgur(dot)com/08eylng(dot)jpg
