I am not sure of made easy material or test series coz i am not a student of made easy, ACE Academy material is unbeatable and its test series too is very challenging, what all i can say is, before joining ACE i was In this post, you will find study material by ACE Academy. Some of the early examples are the process of making fire and instruments using the sun and stars, such as Stonehenge.

Signals which can be completely represented graphically or mathematically are known as deterministic signals.
This means that the nature and value of the signal can be predicted at any point of time. Signals which take random value i. These signals are quite irregular and we cannot represent these signals mathematically.
Example: Noise generated in a communication channel and thermal noise generated in an electrical circuit. Signal which is defined only for non-negative value of time and zero for negative value of time is known as causal signal. Also known as Symmetric and Anti-symmetric asymmetric signal.
A signal x t will be symmetric or even if it satisfies the following condition. A signal x t is also considered symmetrical about the vertical axis then it is also termed as an even signal.

An antenna is a physical device that radiates energy, almost always with some directional dependence. Even an omni-directional antenna will have one or two narrow directions where there is a reduction or a null in the radiated energy. The energy leaving an antenna is also polarized — meaning that the electric field is in a particular orientation. Theoretically, for efficient transfer of energy between two antennas, their respective radiation patterns must be optimized in the correct direction and the antennas must be polarized with the same orientation. However, in the real world, where line of sight LOS between two antennas rarely exists, and at frequencies above about MHz, objects in the path between the antennas walls, structures, people, terrain, etc.
Already loved by students and working engineers everywhere! Books … This book is stunningly good! These study materials are for information purposes and completely free. I wish I had this book when I was studying for my qualifiers. Each chapter provides carefully selected illustrations and examples to make learning or relearning the material as simple as possible. Then you can start reading Kindle books on your smartphone, tablet, or computer - no Kindle device required.
