Which is tough SSC or railway?

The toughness in SSC CGL is greater than that of Railway examination. So if you are preparing for SSC CGL then you will have a good strength in subjects such as Mathematical Ability, English etc. But the logic reasoning in Railways is a bit different from SSC CGL but if you practice well those can be easily equipped.


How does quadrature demodulation work?

In quadrature demodulation, we are converting the existing modulation into the corresponding I/Q baseband signals. It's important to understand that the received signal could be from any sort of transmitter—quadrature demodulation is not limited to signals that were originally created through quadrature modulation.

How do plants breathe in and out for class 3?

Plants do not breathe, so they need to get oxygen through the stomata, the small little holes in their leaves, and also through their roots. In respiration, the oxygen is used to help metabolize and burn the sugars into energy.
