Should I interpolate ENR dB values?

ENR interpolation

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

Re: ENR interpolation

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.
