1
Q
How do regression-based differentiation and integration work when applied to discrete data?
A
A continuous function is fitted to the data, the derivative and integral is then determined of the continuous function
2
Q
What is the order of accuracy of the finite difference derivative approximations?
A
First order for forward and backward, second order for central
3
Q
What are two common methods used in numerical integration
A
Rectangle and trapezoidal rule
4
Q
What is the Nyquist frequency?
A
Maximum observable frequency
5
Q
How is the Nyquist frequency defined?
A
Half of the sampling rate
6
Q
How can bias-induced drifting be mitigated?
A
Using a high-pass filter
7
Q
How can noise be mitigated?
A
Using a low-pass filter
