If 𝜑 𝑡 = 𝑔 (2t) that mean T Will =

What is the operation? we make if ( -t + 5)

Both stations transmit, but only one at a time

Signals are transmitted in only one direction

Both stations may transmit simultaneously

The medium is carrying signals in both directions at the same time

Range of frequencies contained in a signal

Narrow band of frequencies containing most energy

Width of frequency spectrum

Analog -> digital

Digital -> Analog

Digital Data -> Digital Signal

Encoder receives … input/s

Analog -> Analog

The output of Encoder

Data signal is not processed – no amplification, no frequency change, no phase shift

input (baseband) signal is usually centered around 𝑓 = 0

In baseband communication, the data signal undergoes which of the following processes?

What is the purpose of carrier communication?

In baseband transmission, all signals are transmitted at the same frequency band centered around:
