Minimum Detectable Signal (MDS
)
MDS is a level 3 dB
above the noise floor. The value of MDS is calculated with the help of following formula.
MDS = kTBF
k = Boltzmann’s constant
T = Temperature in degree Kelvin
B = Noise Bandwidth
F = Noise Factor
Dynamic Range (DR)
Range of input powers at which a receiver can operate is called dynamic range of the system
Lower End: -
Upper End: -intermodulation products (IP3)
limits the performance of the receiver at the upper end.
A commonly accepted equation/definition for dynamic range is:
