	Logarithmic derivative - Wikipedia, the free encyclopedia
		In mathematics, specifically in calculus and complex analysis, the logarithmic derivative of a function f is defined by the formula
		The logarithmic derivative idea is closely connected to the integrating factor method, for first order differential equations.
		and one can draw the general conclusion that for f meromorphic, the singularities of the logarithmic derivative of f are all simple poles, with residue n from a zero of order n, residue −n from a pole of order n.

		Logarithmic Differential Compression (LDC) ------------------------------------------ Keith Larson, Texas Instruments Inc Method and Apparatus for Signal Compression and Processing Using Logarithmic Differential Compression (LDC) US PATENT #5,933,360 August 3, 1999 -- TI 19500 LDC is a simple, low overhead method of compressing audio and natural signals with minimal impact to quality.
		By using step sizes that are logarithmic, a telephone compander is able to cover a large dynamic range, and still be able to preserve enough harmonic content to be legible.
		Differential Compression ------------------------ For speech or music signals, the harmonic content tends to follow a 1/F rule where lower frequency signals (bass) tend to have larger magnitudes as compared to high frequencies.

		For differential equations over the real numbers, there seems to be a strong connection between having formal solutions in the logarithmic-exponential series and having real non-oscillating solutions at infinity.
		This is a fascinating area requiring a sophisticated mixture of ideas from stability theory, differential algebra, and algebraic geometry.
		In particular, he hopes to work on problems in differential Galois theory and on applying geometric ideas of Hrushovski to understand the geometric behavior of solutions of generic equations.

		An example of this is given by Fauvel and Gray,(1987): Transform the differential a.dz:(bb-zz) into a logarithmic differential a.dt:2bt and reciprocally.
		Corollary: One transforms the differential a.dz:(bb+zz) in the same way into -a.dt:2bt.sqrt(-1), an imaginary logarithmic differential, and reciprocally.
		Johann had found that if f(x) and g(x) are differentiable functions at x = a such that f(a) = g(a) = 0 and the limit (x->a) f'(x):g'(x) exists then, lim(x->a).
