A satellite link has a transmitted power output of 0.5W. This power is increased in the direction of transmission by the transmitter antenna, which has a 20dB gain. The RF signal is attenuated by a path loss of 200 dB. The total noise level at the receiver input is estimated...
I actually have no idea on how would we conduct our statistical analysis for our design project. We will be creating a digital alarm clock with an improvised sensor and we will also be conducting series of tests for it. Now our teacher is looking for the statistical analysis.
Our testings are...
I wonder how can I make the logic gate read 0V when it is open?
For instance, the AND logic gate. If one of its input pin has 5V supply, and the other don't have, the output signal given to me is 5V. How can I make it 0V? Well, theoretically, it should be 0V, but in reality, it appears that...

The Attempt at a Solution
For letter A, my guess is ξ = dɸB/dt, ɸB = BA (since both magnetic field and the area are constants)
After substituting, I ended up with a hanging \frac{d}{dt}..
I'm quite confused.
For letter B, I don't know. Will I use the same...
Well, the attachments says it all, the cap-monster and res-monster maze. I want to know if I made a right decision about my answer.
Cap-monster maze
ξ - q/C = 0
Then q = 60(nano)Coulomb.
Res-monster Maze
-ξ1 - ξ2 - ξ3 - ξ4 + IR = 0
I = 4A.
Am I right?
