NIST Technical Note 1337: Characterization of Clocks and Oscillators

38. Page TN-30There are two errors in eq 6.6. The equation for Flicker PM is missing a square root inthe exponential. It should readFlicker PM= (1 N-l I (2n+I)(N-l)jV,df . . exp n n .2n 4In the equation for Flicker PM, the numerator of the upper term should read 2(N - 2)2instead of 2(N - 2). The equation should readFlicker FM d.f ""2(N-2)2 for n:= 12.3N-4.9'SN 2 for n ~ 24n(N +3n)'39. Page TN-85There are errors in two of the terms of Table 12-4. The small n in the denominator of thefirst logarithmic term for flicker phase should be an ill, and the whole quantity in thesquare bracket should have an exponent of 1/2 . The equation should readFlicker phase exp[IO( ~~ 1 ) IO( (2m + 11(N - 1) )rThe (N - 2) in the flicker frequency term should be replaced by (N - 2)2 so that df is2(N- 2)2Flicker frequency for m:= 1 .2.3N -4.940. Page TN-279There is a factor N missing in the first expression under eq A6. It should readA = 3[3N(N+l)+2] .41. Page TN-307The fifth identity for BI, BI(N, 1,/-,) = 1 for /-' < 0 and = [2/N(N - 1)]..... for /-' > 0,should be deleted. The identity for /-' < 0 is incorrect and that for jJ. > 0 is superfluousconsidering the identity above it which covers all cases for jJ. *- O.TN-343
