ABSTRACT
When a line-of-sight path exists between two antennas, the propagation loss is equal to free-space attenuation. Free-space propagation occurs in the far-field region. (…)

Modulation
A message signal usually spreads over a range of frequencies,called the signal band width.That is why message signals are also called base band signals-representing the band of frequencies of the original signal. (…)

1.Introduction to Amplifiers
In “Electronics”, signal amplifiers are widely used devices as they have the ability to amplify a relatively small input voltage signal, for example from a Sensor or microphone, into a much larger output signal to drive a Relay, lamp or loudspeaker for example. (…)
