hallo
i have a noise source with ENR values at 1 and 2 Ghz in dB
i want to get the values in between
should i interpolat the dB values
or convert to linear scale then interpolat and then get the dB
thanx

Most probably linear interpolation is enough. But you may try second order too.
You can see that the calibration data and decide how "smooth" it is.
I think the uncertainty that may arise in using linear or dB interpolation is much more little (so negligible) than the uncertaunty you have in the ENR value.
