Obviously you haven't worked in the real world of RF and microwave. All spectrum and signal analyzers are calibrated to read directly in dB. For example, displaying a signal and its spurious harmonic which might be 60dB down is impossible to see on a linear scale but is readily displayed on a dB scale.
Hi Carl,
It would also be interesting to see how these 'engineers' would present a Bode plot or FFT plot using a linear Yaxis scaling instead of the log dB scaling.
