We have a periodic signal of period 10 ms and amplitude 2.The signal is a rectangular pulse from -5/2 to 5/2 and 0 from 5/2 to 19/2.This signals fundamental frequency(f0) is 100Hz.It is passed through a filter whose response is 1/(1+jf/f0.I calculated the average power using the trignometric...
Questions:
If you think of the signal spreading out like the surface of a sphere you can see that the area goes up as r^2?
I can't understand that part.Please explain.
Also if i take into account the atmospheric effects then does that mean the relation between power and distance change?If...
Why microwave frequencies are more affected due to rain? How does water actually affect microwaves?And lower frequencies have more diffraction.Why is it so?
