• Bit

Is a measure of how much information can be propagated through a communications system and is a function of bandwidth and transmission time.

• Information Capacity

• Communication System

• Communication Theory

• Information System

is defined as knowledge or intelligence that is Information

communicated between two or more points

• Lyguist Bandwidth

• Nyquist Bandwidth

According to ..... binary digital signals

can be propagated through an ideal noiseless transmission medium at a rate equal to two time the bandwidth of the medium
