Description Equation Unit
1 Frequency = 1/ Hz, cycle per second
2 Period = 1/ Second
Meter (m) or m/s
3 Wavelength λ = Speed; c = 3 x 108
m/s
4 Bandwidth 2− 1 Hz
1 1 2
5 Inverse square law ; = µW
2 1
6 Power loss of a path ∗ ℎ dB
7 Data rate ∗ bit/s, or (baud)
8 number of symbols 2
2 bit
Calculators do not usually give option to calculate log2 of above
9 Number of bit equation, so instead you can use: Note that 0.301 is getting
10 ÷ 0.301
from
Log2/log10 = 0.301029995
