ConvDiffCoef: Convert Differential to Difference Eq. Coefficients

In TDD: Time-Domain Deconvolution of Seismometer Response

Description

Returns difference equation coefficients corresponding to input differential equation coefficients and sample interval.

Usage

ConvDiffCoef(db, dt)

Arguments

db	Vector of differential equation coefficients
dt	Time interval (s)

Details

Input differential equation is of the form db[1] * f(t) + db[2] * f'(t) + db[3] * f”(t)...

Output difference equation is of the form b[1] * x_i + b[2] * x_(i-1) + b[3] * x_(i-2)...

Value

Coefficients of difference equation.
