Power to dB dB = 10 log10(P2 / P1) You know both powers Powers must use the same unit dB to ratio Ratio = 10^(dB / 10) You know gain or loss in dB Negative dB gives a ratio below 1 Voltage to power P ...

The radar range calculator is designed to determine the theoretical maximum detection distance of a radar system, beyond which the target/object can no longer be detected and analysed, based on the ...

Companion collection to OrbitCalc for everyday HF, VHF, and UHF station work: antenna design, transmission lines, power/SWR, and grid square calculations. These programs are small, dependency-free, ...

The Fourier transform can be used to convert a solution to Maxwell’s equations for an arbitrary frequency ω into a solution for arbitrary time dependence. The electric and magnetic current sources, J¯ ...
