Unformatted text preview: dest /P src ) P dest : Signal Power at destination P src : Signal power at source 2) Distortion: Signal changes in form / shape. Composite signal components have different propagation speed through the medium; hence destination arrivals delays/phase shifts causing incorrect receiving of the original signal at the destination. 3) Noise: i) Thermal (white) caused by elections random movement in the medium (extra superimposed signals) ii) Induced: Caused by appliances acting as a sending antenna with medium as receiving one iii) Crosstalk: Mutual affect between wires acting as sending/ receiving antenna iv) Impulse: caused by a power lines, lightning shaped as a “spike” (high frequency on very short time)...
