What is a discrete difference equation?
In the case of discrete difference equation models, a number x∗ is called an equilbrium point or fixed point of the difference equation xn+1 = f(xn) if x∗ = f(x∗).
What is a discrete-time equation?
Mathematically, we use the notation y = S[x] to denote a discrete-time system S with input signal x[n] and output signal y[n]. Notice that the input and output to the system are the complete signals for all time n.
What is differential equation in DSP?
The difference equation is a formula for computing an output sample at time based on past and present input samples and past output samples in the time domain.
What is the difference equation method?
A difference equation is any equation that contains a difference of a variable. The classification within the difference equations depends on the following factors. • Order of the equation. The order of the equation is the highest order of difference contained in the equation.
