- Physical Channel
Constraints on what kinds of signal can be transmitted
Data rate limits => maximum data rate
1. Signal Power
2. Noise Power
3. Distortion
Without distortion or noise, R will have ꝏ value and the power of error (Pe) approach to 0.
Gaussian Noise Formula :
C= 1/2 B Log ( 1+SNR )

Signal => Continous, Discrete, Complex, Real
Signal’s Characteristic
1. Power
2. Bandwith

Whats’s noise ?
Any unwanted component of signal
a. Internal/ Thermal Noise => Additive (White Gaussian)
b. Distortions
c. External Interface
