Final Cards Flashcards
1
Q
Formula for transmission delay
A
T = (N^Σ i = 1 (L/Ri) )+ (L/Rslow)(M - 1) T = Time N = number of links L = number of packet bits R = Bits per second M = number of packets
2
Q
y = a*cos(bx)
A
a = amplitude period = 2π/b frequency = b/2π
3
Q
Round trip propagation formula
A
RTP = 2* D/Ps D = distance (only one way tho) Ps = propagation speed
4
Q
3 points about thermal noise
A
> Approximately white i.ei all frequency components contribute equally
Thermal noise depends on temperature
Thermal noise can induce bit errors
