Real-time CalculationsTelecommunication Constants
Decibels (dB) are logarithmic units expressing power ratios. A 3 dB change doubles or halves the power. A 10 dB change corresponds to a factor of 10.
Shannon-Hartley Theorem establishes the absolute maximum error-free data rate (capacity) for a noisy communication channel.
Velocity Factor (VF) is the speed of electromagnetic waves in a transmission line relative to their speed in vacuum. For example, light travels ~31% slower inside fiber glass than in empty space.
