Non-linearity in the Freq. Measurement

ν frequency

x line in recording milliammeter

Measure rate in units of KC/line (= dν/dx)

Assume the rate vary linearly (not uniformly)
with frequency in an interval of 25 KC.

ν₀ = [?] freq.

ν₁ = final "

where a(ν₀ = rate at frequency ν₀

per line

Integration of (1) gives
