ABSTRACT

D. W . Allan showed that if y(t) is a sample function of a random U

noise process with a power law spectral density (i. e . , S (f) = h I f I ),

then there is generally bias to the estimated variance of y, defined as Y

N 2 Y N- 1 0 (N, T , T ) = -

n= 1

where N is the number of samples, 7 is the average value of y(t) over

the n-th interval of duration T , T is the time between the beginnings of

any two successive sample intervals, and

of the estimated variance i s proportional to T’ where p is a constant

related to a, the exponent in the spectral density; i. e . ,

TABLES OF BIAS FUNCTIONS, B1 AND B2, FOR VARIANCES

BASED ON FINITE SAMPLES OF PROCESSES WITH POWER

LAW SPECTRAL DENSITIES

Consider a random variable y with mean m. .The variance of y is

defined as the expectation value of (y - m) 2 , that is

V a r y E E[(y - m) 2 1 .

This is defined as an average over the entire ensemble but, for an

ergodic process, y(t),it can alternatively be defined as an average over

all time, t .

Typically, the variance of y is estimated from a finite set of

experimental values according to the relation

N

i= 1

where <y>= - 5 yi is the mean of the y.. The factor - 1 is used in N- 1 1

i= 1 order that the estimate have no bias for non-correlated y: that is, one

typically wants to obtain the true variance which would be obtained as

N - m . For finite N, the estimated variance has some expected value,

If the y. a r e independent (actually, non-correlated is sufficient) random

variables, then the expected value of this estimated variance for finite 1

related, however, the estimate based on (1) may indeed be biased.

This fact has been recognized and discussed in some detail for the case

of power law spectral densities by Allan [ 11.

If the y. a r e cor - 1

We assume that y(t) has a spectral density,

where h is a constant, the limit frequencies fe and f satisfy the relations U

and any intervals of time, At, of any significance satisfy the relations

In short , y(t) has a power law spectral density over the entire range of

significance.

Consider a measurement process which determines an average

value of y(t) over the interval t to t t 7 . That is,

T(t) = - y(t ')dt' .

One, now, may determine an estimated variance from

measurements spaced every T units of time; that i s ,

This mapping involves a simple extension of Allan's work [ 11 to the

range O < p < 2 . This extension was also mentioned in [SI.

Allan [ 13 considered in some detail the case where T = T . This

i s the case of exactly adjacent sample averages--no "dead time" between

measurements. Allan defined a function, X (N, p), as follows

infer p and hence the spectral type by use of the mapping of Figure 1.

Since many experiments actually have-dead time present, i t is of

value to make two different extensions of this function, X (N, p). Firs t ,

define B ( N , r , p ) by the relations 1

In words, B is the ratio of the expected variance for 1

It is apparent that B (N, r = 1, p) 1 E X (N, t.).

For the conditions given above and with reference to Allan [l],

one may write expressions for both B and B 1 2’ as follows:

Examdes of the use of the bias functions

The spectral type, that is , the value of p, may be inferred by

varying T, the sample time [I, 21. Another useful way, however, of

determining the value of p i s by using B (N, r, p ) as follows: calculate

an estimate of E 0 and of E D 2 (2, T, T ) and hence B (N, r , p);

then by use of the tables the value of p may be inferred.
