Electrical noise is defined as any undesirable electrical energy. Figure
57 shows the effect of noise on an electrical signal.

RF engineering is very important in our daily activities.
We need radio and television for entertainment and nowadays,
we cant live without the mobile phone.
Why RF is so important?

1.4 Power Measurements
The decibel (dB) is a logarithmic unit that can be
used to measure ratios of virtually anything. In
the electronic communications, the decibel

Radio Frequency Transmission
Information signal are transported between a transmitter and a
receiver over some form of transmission medium.

Comparison Between AM and FM Reception
Frequency modulation causes a carrier frequency to
deviate from its rest value by an amount linearly
proportional to the voltage of a baseband sig
